Module 1.1: Cloud Concepts Overview

Cloud computing is the on-demand delivery of compute power, database storage,
applications, and other IT resources through a cloud services platform via the internet, with
pay-as-you-go pricing.
The most basic way to define what the “cloud” is that it is a computer located somewhere
else that is accessed via the Internet and utilized in some way. Web services is also another
name for what people call the cloud.
The cloud is comprised of server computers located in large data centers in different
locations around the world. When you use a cloud service like Amazon Web Services (AWS),
you are utilizing the computers owned by AWS. AWS is a cloud services provider.

The computers contain various technology features and services, like building blocks, that can
be used to assemble solutions that help a user meet their business goals and technology
requirements. With cloud computing, organizations can consume on-demand computing and
storage resources rather than building, operating, and improving infrastructure on their own.

Module 1.1: Cloud Concepts Overview

Cloud computing enables you to stop thinking of your infrastructure as hardware, and instead
think of it (and use it) as software. Before cloud computing, you would have to provision
capacity based on guessing theoretical maximum peaks. If you didn’t meet your projected
maximum peaks, or you exceeded them, you would be paying for expensive resources that
would stay idle or have insufficient capacity to meet your needs.

© 2018 Amazon Web Services, Inc. or its affiliates All rights reserved.

10

AWS Academy

Module 1.1: Cloud Concepts Overview

Managing hardware takes away time and resources you could be using to improve your
architecture and your application. Hardware solutions are physical. This means they require
space, staff, physical security, planning and capital expenditure.
You have to guess at theoretical maximum peaks, asking if there is enough resource capacity
or if you have sufficient storage. What if your needs change? You have to go through the
time, effort, and cost required to change all of these.
For example, if you want to provision a new web site, you would have to go out and buy the
hardware, rack and stack it, put it in a data center, and then manage it or have someone else
manage it. This approach is very expensive.

Cloud computing addresses some of the issues in the traditional computing model. One of
the most prohibitive aspects of traditional computing is the significant up-front investment of
acquiring, provisioning, and maintaining on-premises infrastructure. Cloud computing can get
businesses up and running with a new solution in place quickly and with very low up-front
costs. Then, you can elastically scale up and down in an automated fashion so that you pay
only for what you use.
Cloud computing also allows you to select the services that best match your needs, giving you

flexibility with a wide range of choices and the ability to change your configuration at will. All
of these services are provided on a secured infrastructure.

AWS Academy

Module 1.1: Cloud Concepts Overview

Accessing and using your infrastructure as software offers a number of benefits-flexibility in
particular. If your needs change, your software can change much more quickly, easily, and
cost-effectively than your hardware.
With a cloud services provider like AWS, you don't have to anticipate your hardware needs
ahead of time and then order, install, and set it up at your data center. You also don’t need to
undergo a long procurement cycle. With a few clicks, you can provision exactly what you
need-and it will be available to you in a few minutes.
That means you can provision and terminate resources as necessary on AWS, instead of
paying for hardware when you’re not using it. You can treat resources as temporary and
disposable resources, free from the inflexibility and constraints of a fixed and finite IT
infrastructure.
By harnessing the power of AWS, you can be more agile and efficient with change
management, testing, reliability, and capacity planning.

AWS Academy

Module 1.1: Cloud Concepts Overview

Cloud services can fall into one of three primary categories, based mainly around how much
control and responsibility you have over how the service is configured.

With IaaS (or Infrastructure as a Service), you manage the server, which can be
physical or virtual, as well as the operating system (Windows or Linux). In general, the
data center provider has no access to your server.
Basic building blocks for cloud IT include:
• Networking features
• Compute, and
• Data storage space

With PaaS (or Platform as a Service), someone else manages the underlying
hardware and operating systems. This enables you to run applications without
managing underlying infrastructure (for example -- patching, updates, maintenance,
hardware and operating systems). PaaS also provides a framework for developers
that they can build upon to create customized applications.
With SaaS (or Software as a Service), you manage your files, while the service
provider takes care of all of the data centers, servers, networks, storage,

14

AWS Academy

Module 1.1: Cloud Concepts Overview

maintenance, patching, etc. All you worry about is the software and how you want to
use it. You are provided with a complete product that is run and managed by the
service provider. Facebook and Dropbox are examples of SaaS. You manage your
Facebook contacts and Dropbox files, and the service providers manage the systems.

Module 1.1: Cloud Concepts Overview

Now, let’s reveal the three cloud deployment models.

"All-In" Cloud is a cloud-based application that is fully deployed in the cloud, and all parts of
the application run in the cloud. Applications in the cloud have either been created in the
cloud or have been migrated from an existing infrastructure. Cloud-based applications can be
built on low-level infrastructure pieces (for example, networking, compute or storage) or can
use higher-level services that provide abstraction from the management, architecting, and
scaling requirements of core infrastructure.
A hybrid deployment is a way to connect infrastructure and applications between cloudbased resources and existing resources that are not located in the cloud. The most common
method of hybrid deployment is between the cloud and existing on-premises infrastructure
(sometimes called on-prem). On-premises infrastructure is located within the physical
confines of an enterprise, often in the company's data center. A hybrid deployment model is
used to extend an organization's infrastructure into the cloud while connecting cloud
resources to an internal system. For more information on how AWS can help you with your
hybrid deployment, visit the link https://aws.amazon.com/enterprise/hybrid/.
When you run a cloud infrastructure from your own data center, that’s called on-premises or
private cloud. While this kind of deployment lacks many of the benefits of cloud computing, it
does provide dedicated resources and is a popular choice for organizations who need to meet
certain compliance standards. In most cases, this deployment model is the same as legacy IT

infrastructure while using application management and virtualization to increase resource

AWS Academy

Module 1.1: Cloud Concepts Overview

Let’s take a closer look at capacity in the All-In Cloud and On-Premises solutions.

In the “All In” solution, capacity is in sync with demand. Resources are provisioned and
decommissioned in response to demand with only a couple clicks.
In contrast, in “On-Premises” deployments, because you rely on physical hardware, you have
to forecast your capacity needs well in advance of the actual demand. Instead of resources
that expand and contract with demand, the on-premises solution results in idle, wasted
resources waiting for demand to catch up. If demand suddenly outpaces capacity, the
shortfall may result in unhappy customers. Your ability to respond quickly to this situation
can be limited by long procurement cycles or by constraints on where you house your IT
resources. Furthermore, building an on-premises infrastructure can be slow and expensive.

18

12

AWS Academy

Module 1.1: Cloud Concepts Overview

To summarize:
• With the All-In solution, there is no upfront investment, so you avoid the large capital purchases
required for an On-Premises solution. You have immediate access to resources without having to
procure, install, and configure cabling, racks, servers, and storage in a physical location with
appropriate facilities like cooling and power. Instead, you just click to order and pay for the
resources you need, which are available almost immediately.
• Cloud computing helps you reduce ongoing IT costs in multiple ways. AWS continually lowers prices
due to massive economies of scale and continual improvements. Multiple pricing options also help
you optimize costs based on your unique workloads. You pay only for what you use on a variable,
monthly basis. On-premises solutions typically require upgrades on 1-year, 3-year, or 5-year cycles.
• Cloud gives you managed IT resources on demand, at a fraction of the cost of traditional
infrastructure. This cost savings empowers organizations to shift resources toward innovative new
projects that grow their business by focusing on “apps not ops.”
• Predicting how customers are going to adopt your new application is complex, making it difficult to
estimate your infrastructure capacity needs. Flexible capacity means that your resources are
dynamic. You can quickly provision resources as demand goes up and turn off what you don’t need
as demand declines.
• Cloud computing’s speed and agility makes it possible for you to respond to changing market
conditions. With AWS, resources can be provisioned as needed. This self-service environment
changes how you develop and deploy applications, allowing your team to experiment more quickly

19

Module 1.1: Cloud Concepts Overview

and more frequently. The amount of time it takes to get a server procured, delivered, and
running limits this in a traditional infrastructure.
• With on-premises, it is hard to deliver great performance to a distributed user base. The
initial purchase is large, it’s labor intensive with patches, upgrade cycles and systems
administration with fixed capacity. There are long procurement cycles and setup, so
companies focus on one geographic region at a time to save costs and time. Without
geographical limitations, you can deploy your application in any of the AWS regions
around the world with lower latency and at minimal cost.

You can use a cloud computing platform for the following:
• Application Hosting for an on-demand infrastructure to host internal or SaaS applications.
• Backup and Storage to store data and build dependable backup solutions.
• Content Delivery to distribute content worldwide, with high data transfer speeds.
• Host static and dynamic websites.
• Enterprise IT to host internal- or external-facing IT applications in AWS's secure
environment.
• Use a variety of scalable database solutions, from hosted enterprise database software to
non-relational database solutions.

Module 1.1: Cloud Concepts Overview

Now let’s review some important cloud terminology. High availability, fault tolerance,
scalability, and elasticity are four terms often used when discussing the cloud. These
concepts are the fundamental building blocks of AWS and will be referred to throughout the
course.
High availability refers to a resource that is accessible when you attempt to access it. For
example, if every time you go to the ATM to make a withdrawal it works as expected the
ATM is highly available; however, if you go to use it and there is a sign on the front that says
“Out of Order”, it is not highly available.
Fault tolerance is the ability to withstand a certain amount of failure and still remain
functional. It also refers to the ability of a system to be self-healing and return to full capacity
despite a failure. It is the ability of a system to fail in some way but still remain functional.
Scalability is the ability to easily grow in size, capacity, and/or scope when required
particularly in response to demand. If something cannot quickly grow in an easy manner it is
not scalable.
Elasticity is the ability to not only grow (or scale) when required, but also to reduce or
contract in size as needed. A system that is elastic can scale to grow as needed usually based

on demand and contract as demand decreases.

In summary, cloud computing is the on-demand delivery of IT resources online with pay-asyou-go pricing.
The three models of cloud computing are:
Infrastructure as a Service (IaaS)
Platform as a Service (PaaS), and
Software as a Service (SaaS)
All-in cloud, hybrid, and private cloud, are three cloud deployment models.
Cloud services are available to replace traditional on-premises computing activities.

Why are so many companies interested in moving to the cloud? Let’s take a look at the six
benefits companies can realize by moving to the cloud.

26

AWS Academy

Module 1.1: Cloud Concepts Overview

Advantage 1: Trade Capital Expense for Variable Expense

The first advantage is to trade capital expense for variable expense.
Instead of having to invest heavily in data centers and servers before you know how
you’re going to use them, you can pay only when you use computing resources, and
pay for how much you use.

27

AWS Academy

Module 1.1: Cloud Concepts Overview

Capital expenses, or capex, are funds used by a company to acquire, upgrade, and maintain
physical assets such as property, industrial buildings, or equipment.
Remember the data center example where we racked and stacked the hardware and then
had to manage it all? You have to pay for everything in the data center whether you use it or
not. Furthermore, when you purchase a hardware solution, you cannot take advantage of the
same massive economies of scale that Amazon can.
A variable expense is an expense that is easily altered or avoided by the person bearing the
cost. By using the cloud, businesses won’t have to invest money into data centers and
servers, and can pay for only what they use in a pay-as-you-go fashion. This lets businesses
save money on technology and enables them to adapt to new applications with as much
space as needed in minutes, rather than weeks or days. Maintenance is reduced so the
business can spend more time focusing on the core goals of the business.

AWS Academy

Module 1.1: Cloud Concepts Overview

Data centers require hardware solutions, which are physical, and require space, staff,
and physical security. Significant cost and time is associated with the procurement of
these resources. Additionally, purchasing power is limited to the size of their
individual purchases.
In contrast, with usage from hundreds of thousands of customers are aggregated in
the cloud, providers such as Amazon Web Services can achieve higher economies of
scale, which translates into lower pay as-you-go prices.

AWS Academy

Module 1.1: Cloud Concepts Overview

Before cloud computing, we had to guess about how much resources would be
required to accommodate maximum usage peaks. That method also assumed that
you could accurately predict the usage peaks, if there’s enough resource capacity and
if the amount of storage is sufficient. When you guess, it is very likely that you will
probably either buy too much or too little. If you buy too much, you’ve wasted
money. If you buy too little, you will have downtime.
With cloud computing, these problems go away. You can access as much or as little as
you need, and scale up and down, scale in and out as required with only a few
minutes notice.

Advantage 4: Increase speed and agility.
Advantage four is increased speed and agility.
In a cloud computing environment, new IT resources are only a click away, which
means you reduce the time it takes to make those resources available to your
developers from weeks to just minutes. This results in a dramatic increase in agility
for the organization, since the cost and time it takes to experiment and develop is
significantly lower.

AWS Academy

Module 1.1: Cloud Concepts Overview

Cloud services provide instant global reach and rapid availability of new resources
that enables you to quickly change or scale your technology in minutes, not weeks.
Organizational agility is a core differentiator in today’s rapidly changing business
environment. For organizations to succeed in a constantly changing world, they need
to improve their ability to change and adapt.
You can safely experiment with new ideas and encourage innovation at a very low
cost and leverage pre-fabricated functionality without requiring in-house expertise,
such as data warehousing and analytics.

You may even find success with ideas that simply weren’t feasible in the past due to
hardware or budget constraints. You’re able to explore new avenues of business with
minimal risk and expense, and can test with different configurations.

A web service is any piece of software that makes itself available over the Internet or
on private (intranet) networks. A web service uses a standardized format (such as
XML or JSON) for the request and the response of an API interaction. It is not tied to
any one operating system or programming language, it’s self-describing via an
interface definition file and is discoverable.

Module 1.1: Cloud Concepts Overview

The array of AWS services can be intimidating as you start your journey into the
cloud. Initially, you only need to focus on a few ”core” services. You will need to
understand the AWS Global Infrastructure, several Compute services, Networking &
Content Delivery, Storage, Databases, Security & Identity Access Management, and,
finally, Management Tools. Specifically, you should understand the following services
from the core service group:
• Compute -- including Amazon Elastic Compute Cloud (or Amazon EC2), AWS
Lambda, and AWS Elastic Beanstalk.
• Networking -- including Amazon Virtual Private Cloud (or VPC), Amazon Route 53,
and Domain Name Services.
• Storage -- including Amazon S3 (or Simple Storage Service), and Amazon Glacier.
• Databases -- including Amazon RDS (or Relational Database Service), and Amazon
DynamoDB (or Non-Relational Database).

47

AWS Academy

Module 1.1: Cloud Concepts Overview

You may wonder how to access this broad array of services. You can access them in
any of three ways: using the AWS Management Console, the AWS Command Line
Interface (AWS CLI), and via Software Development Kits (SDKs). For access on the go,
you can use the AWS Console Mobile App to quickly view resources on the go.
The AWS Management console breaks down AWS services into separate categories,
like Compute, Management Tools, Mobile Services, etc. Each category has a number
of different services in it, and all of the services can be accessed from the console.
For example, the Compute category contains Amazon EC2, Amazon EC2 Container
Service, Amazon Lightsail, AWS Elastic Beanstalk, AWS Lambda, and AWS Batch.

The AWS CLI is a unified tool to manage your AWS services. With just one tool to
download and configure, you can control multiple AWS services from the CLI and
automate them through scripts. The CLI User Guide instructs you on how to install
and configure the tool. After that, you can begin making calls to your AWS services
from the CLI.
Simplify using AWS services in your applications with an Application Programming
Interface (or API) tailored to your programming language or platform.

AWS Professional Services created the AWS Cloud Adoption Framework (AWS CAF) to
help organizations develop efficient and effective plans for their cloud adoption
journey. The guidance and best practices provided by the framework help you build a
comprehensive approach to cloud computing across your organization, and
throughout your IT lifecycle.
The AWS CAF breaks down the complex process of planning a move to the cloud into
manageable pieces called perspectives. Perspectives represent essential areas of
focus that span people, processes, and technology. Capabilities within each
perspective identify which areas of your organization require attention. From that,
actions are organized into prescriptive work streams that support a successful cloud
journey.
The AWS Cloud Adoption Framework provides guidelines for establishing, developing,
and running AWS environments. You’ll receive guidance that supports each unit in
your organization so that each area understands how to update skills, adapt existing
processes, and introduce new processes to take maximum advantage of the services
provided by cloud computing.

Module 1.2: Cloud Economics

There are three fundamental characteristics you pay for with AWS: compute, storage,
and outbound data transfer. These characteristics vary slightly depending on the
AWS product you are using. However, these are the core characteristics that have the
greatest impact on cost.
There is no charge for inbound data transfer or for data transfer between other AWS
services within the same AWS Region, although there is a charge for aggregated
outbound data transfer.
The outbound data transfer is aggregated across:
Amazon Elastic Compute Cloud (or Amazon EC2),
Amazon Simple Storage Service (or Amazon S3),
Amazon Relational Database Service (or Amazon RDS),
Amazon SimpleDB,
Amazon Simple Queue Service (or Amazon SQS),
Amazon Simple Notification Service (or Amazon SNS), and
Amazon Virtual Private Cloud (or Amazon VPC), and then charged at the outbound
data transfer rate. This charge appears on the monthly statement as AWS Data
Transfer Out.

AWS Academy

Module 1.2: Cloud Economics

This philosophy is what underlies AWS pricing. While the number and types of
services offered by AWS have increased dramatically, our philosophy on pricing has
not changed. At the end of each month, you pay for what you use. You can start or
stop using a product at any time. No long-term contracts are required.
AWS offers a range of cloud computing services. For each service, you pay for exactly
the amount of resources you actually need. This utility-style pricing model includes:
•
•
•
•

Pay for what you use,
Pay less when you reserve,
Pay less when you use more, and
Pay even less as AWS grows

Let’s take a closer look at these core concepts of pricing.

Unless you build data centers for a living, you have likely spent too much time and
money building them. With AWS, you pay only for the services you consume with no
large upfront expenses. You’re able to lower variable costs, so you no longer need to
dedicate valuable resources to building costly infrastructure, including purchasing
servers, software licenses, or leasing facilities.
Quickly adapt to changing business needs and redirect your focus on innovation and
invention by paying only for what you use and for as long as you need it. All AWS
services are available on demand, require no long-term contracts, and have no
complex licensing dependencies.

Module 1.2: Cloud Economics

For certain services like Amazon EC2 and Amazon RDS, you can invest in reserved
capacity. With Reserved Instances, you can save up to 75 percent over equivalent ondemand capacity. Reserved Instances are available in 3 options:
• All up-front reserved instance (or AURI)
• Partial up-front reserved instance (or PURI), and
• No upfront payments reserved instance (or NURI)
When you buy Reserved Instances, the larger the upfront payment, the greater the
discount. To maximize your savings, you can pay all up-front and receive the largest
discount. Partial up-front RIs offer lower discounts but give you the option to spend
less up front. Lastly, you can choose to spend nothing up front and receive a smaller
discount, allowing you to free up capital to spend in other projects.
By using reserved capacity, your organization can minimize risks, more predictably
manage budgets, and comply with policies that require longer-term commitments.

With AWS, you can get volume based discounts and realize important savings as your
usage increases. For services like Amazon S3, pricing is tiered, meaning the more you
use, the less you pay per GB. In addition, data transfer IN is always free of charge.
Multiple storage services deliver lower storage costs based on your needs. As a result,
as your AWS usage needs increase, you benefit from the economies of scale that
allow you to increase adoption and keep costs under control.
As your organization evolves, AWS also gives you options to acquire services that help
you address your business needs. For example, the AWS storage services portfolio
offers options to help you lower pricing based on how frequently you access data and
the performance you need to retrieve it. To optimize your savings, choose the right
combination of storage solutions that help you reduce costs while preserving
performance, security and durability.

AWS is constantly focused on reducing data center hardware costs, improving
operational efficiencies, lowering power consumption, and generally lowering the
cost of doing business.
These optimizations and AWS’s substantial and growing economies of scale result in
passing savings back to you in the form of lower pricing. Since 2006, AWS has
lowered pricing 61 times!
Another benefit of AWS growth is that future, higher performing resources replace
current ones for no extra charge.

AWS also offers a variety of services for no additional charge.

• Amazon VPC lets you provision a logically isolated section of the AWS Cloud where you can launch
AWS resources in a virtual network that you define.
• AWS Identity and Access Management (or IAM) controls your users’ access to AWS services and
resources.
• Consolidated Billing is a billing feature in AWS Organizations to consolidate payment for multiple AWS
accounts or multiple AISPL accounts. Consolidated billing provides:
• One bill for multiple accounts.
• The ability to easily track each account’s charges.
• The opportunity to decrease charges as a result of volume pricing discounts from combined
usage.
• And you can consolidate all of your accounts using Consolidated Billing and get tiered benefits.
• AWS Elastic Beanstalk is an even easier way for you to quickly deploy and manage applications in the
AWS cloud.
• AWS CloudFormation gives developers and systems administrators an easy way to create a collection
of related AWS resources and provision them in an orderly and predictable fashion.
• Automatic Scaling automatically adds or removes resources according to conditions you define. The
resources you are using increase seamlessly during demand spikes to maintain performance and
decrease automatically during demand lulls to minimize costs.

dramatically, our philosophy on pricing has not changed. At the end of each month, you pay
only for what you use, and you can start or stop using a product at any time. No long-term

Now that you understand the AWS pricing philosophy and how different AWS services
are priced, let’s take a look at Part 2: Total Cost of Ownership.
In addition to prices, businesses often want to understand the total cost of
ownership, which is a financial estimate that helps buyers and owners determine the
direct and indirect costs of a product or system. It reflects the purchase price of an
asset plus the costs of operation. Total cost of ownership information is especially
helpful when you are making the decision of whether or not to deploy on Amazon
Web Services.
Let’s move forward to the final part of our economic discussion and review both TCO
and the TCO Calculator.

Module 1.2: Cloud Economics

On-premises versus cloud is a question being asked by many businesses. The difference
between these two options is how they are deployed.
An on-premises infrastructure is installed locally on a company’s own computers and servers.
There are several fixed costs, also known as capital expenses, associated with the traditional
infrastructure including facilities, hardware, licenses, and maintenance staff. Scaling up can
be expensive and time consuming. Scaling down does not reduce fixed costs.
A cloud infrastructure is purchased from a service provider who builds and maintains the
facilities, hardware, and maintenance staff. A customer pays for what is used. Scaling up or
down is simple. Costs are easy to estimate because they depend on service usage.

It is difficult to compare an on-premises IT delivery model with the AWS cloud. The two are
so very different that they use different languages.
On-premises IT is a discussion based on capital expenditure, long planning cycles, and
multiple components to buy, build, manage, and refresh over time.
AWS is a discussion about flexibility, agility, and consumption based costs.
So, how can we identify the best option?

© 2018 Amazon Web Services, Inc. or its affiliates All rights reserved.

74

AWS Academy

Module 1.2: Cloud Economics

We can identify the best option by comparing the on-premises solution to a cloud solution.
Total Cost of Ownership (or TCO) is a tool that can be used for this comparison. TCO is a
financial estimate intended to help buyers and owners determine the direct and indirect
costs of a product or system. TCO includes the cost of a service plus all the costs associated
with owning the service.
In the cloud environment, TCO is used for comparing the costs of running an entire
infrastructure environment for a specific workload in an on-premises or co-location facility,
to the same workload running on a cloud-based infrastructure. This comparison is done for
budgeting purposes or to build a business case for business decisions regarding the optimal
deployment solution.

AWS Academy

Module 1.2: Cloud Economics

So, what are some of the costs associated with data center management? These costs include:
• Server costs for both hardware and software, along and facilities costs to house the equipment.
• Storage costs are associated with the hardware, administration and facilities.
• Network costs are similar to the storage costs and include hardware, administration, and
facilities costs.
• And IT labor costs that are required to administer the entire solution.
When comparing an on-premises to cloud solution, it is important to accurately assess the true
costs of both options. With the Cloud, most costs are upfront and readily calculated. For example,
cloud providers give transparent pricing based on different usage metrics, such as RAM, storage,
and bandwidth, among others. Pricing is frequently fixed per unit of time.

Customers gain certainty over pricing and are then able to readily calculate costs based on several
different usage estimates.
Compare this to on-premise technology. Although they are sometimes difficult to determine,
calculations of in-house costs must take into account all:
• Direct costs that accompany running a server like power, floor space, storage, and IT
operations to manage those resources
• Indirect costs of running a server like network and storage infrastructure

Please note that this diagram is conceptual and does not include every cost item. For
example, depending on the solution you are implementing, software costs can include
database, management, and middle-tier costs. Facilities costs can include upgrades,
maintenance, building security, taxes, and so on. IT labor costs can include security admin
and application admin costs. This is an abbreviated list to demonstrate the type of costs that
are involved in data center maintenance.

Let’s take a look at a cost comparison. This example shows a cost comparison for an onpremises and cloud solution over 3 years. For this comparison, two similar environments
were constructed to represent the on-premises and AWS environments. Note that additional
direct and indirect costs associated with the on-premises solution have not been included.
The components of the on-premises solution include:
• 1 virtual machine with 4 CPUs, 16 GB of RAM, and a Linux operating system
• Average utilization is 100%
• Optimized by RAM
The components of a comparable AWS environment include:
• 1 m4.xlarge instance with 4 CPUs, 16 GB of RAM,
• The Instance type is a 3 year partial upfront reserved instance

The cost difference between these solutions is significant - a 96% annual savings on cloud
infrastructure versus an on-premises solution. The three year total savings would be
$159,913!
The on-premise three year total solution cost is $502,266. The AWS Cloud three year total
solution cost is $22,537 for a 96% savings. This comparison helps a business clearly
understand the differences between the alternatives.

AWS Academy

Module 1.2: Cloud Economics

So, what is the difference in the costs?
Remember, the on-premises solution is “predicted” and then continues to incur costs
whether or not the capacity is utilized.
In contrast, the AWS solution is commissioned when needed and decommissioned when the
resources are no longer in use, resulting in the lower overall costs.

automatically.
The calculator incorporates a wide array of pricing calculations across all services in all
regions. It also shows a breakdown of features for each service in each region.
The Simple Monthly Calculator is a tool that helps you:
Estimate monthly services costs when using AWS
Identify opportunities for cost reduction
And use templates to model solutions to compare services and deployment models
The calculator also shows common customer samples and their usage. You can click on the
“Disaster Recovery and Backup” sample or “Web Application” sample and see the uses of

The AWS TCO Calculator helps you evaluate the total cost of ownership of a solution.
Eliminating the need to invest in large capital expenditures, or capex, and providing a pay-asyou-go model that empowers you to invest in the capacity you need, and use it only when
you require it, helps reduce total cost of ownership.
The TCO calculator is a tool that helps you:
• Estimate cost savings when using AWS
• Uses a detailed set of reports, which can be used in executive presentations.
• And modify assumptions that best meets your needs.
An additional benefit of the calculator includes the ability to weigh the financial

Hard benefits include reduced spending on compute, storage, networking and security. Avoid
hardware and software purchases and reductions in operational costs, backup and disaster
recovery and a reduction in operations personnel.
Cloud Total Cost of Ownership defines what will be spent on the technology after adoption or what it costs to “run the engine”. Typically, a TCO analysis looks at the “as is” on-premises
infrastructure and compares this with the cost of the “to be” infrastructure state in the cloud.
While this is easy to calculate, it may only provide a narrow view of the total financial impact
of moving to the cloud.
A Return on Investment analysis can be used to determine the value generated while taking
spending and saving into consideration. This analysis starts by identifying the hard benefits in
terms of direct and visible cost reductions and efficiency improvements.
Next, soft savings are identified. Soft savings are value points that are challenging to
accurately quantify but can be more valuable than the hard savings. It is important for you to
understand both hard and soft benefits to understand the full value of cloud. Soft benefits
include:
• Reusing service and applications that allow you to define, and redefine solutions using the
same cloud service

Background:
Delaware North originated in 1915 as a peanut and popcorn concessions vendor; today, it’s a
major food and hospitality company. Although the company deliberately keeps a low profile,
it is a leader in the food-service and hospitality industry.
Delaware North serves more than 500 million customers annually at more than 200
locations around the world, including venues as diverse as the Kennedy Space Center in
Florida, London Heathrow Airport, Kings Canyon Resort in Australia, and the Green Bay
Packers’ Lambeau Field in Wisconsin. This global presence has turned Delaware North into a
$3 billion enterprise.

AWS Academy

Module 1.2: Cloud Economics

The company’s on-premises data center was becoming too expensive and inefficient to
support its global business operations.
Kevin Quinlivan, Delaware North’s Chief Information Officer, says, “As the company
continued to grow, the demand to rapidly deploy new solutions to meet customer
requirements increased as well. This fact, combined with the need to constantly upgrade
aging equipment, required an even greater commitment of resources on our part. We had to
find a better strategy.”
Delaware North turned to AWS for a solution.

AWS Academy

Module 1.2: Cloud Economics

After a successful migration of about 50 websites to AWS in 2013, Delaware North evaluated
the cost benefit and total cost of ownership to move their IT infrastructure to AWS. Their
focus was to answer C-Suite level business demands for measurable benefits that could
convince an executive committee that the AWS cloud was the right approach.
The evaluation process centered on three criteria:
• First, a cloud solution needed a broad set of technologies that could handle all of
Delaware North’s enterprise workloads while delivering support for critical functions.
• From an operational perspective, Delaware North wanted the features and flexibility to
modify core IT processes to improve efficiencies and lower costs. This included
eliminating redundant or time-consuming tasks like patching software and pushing test
and development tasks through outdated systems that, in the past, added months to the
deployment of new services.
• Finally, financial requirements needed to demonstrate a return on investment with a
solid cost-benefit justification for moving away from their existing data center
environment.

AWS Academy

Module 1.2: Cloud Economics

A cost comparison completed by Delaware North demonstrated that it could save 3.5 million dollars
based on a five-year run rate by moving its on-premises data center to AWS and using three-year
Amazon EC2 Reserved Instances and Reserved Instance renewals.
Quinlivan noted that the deep technology stack available on AWS was more than sufficient to meet the
company’s technical and operational requirements. The pricing structure of the AWS offerings, which
includes paying only for what is used, provided total cost of ownership benefits which was presented
to senior leaders.
Quinlivan stated, “We compared the costs of keeping our on-premises data center versus moving to
the AWS cloud, measuring basic infrastructure items such as hardware cost and maintenance.” He also
says “We estimate that moving to AWS will save us at least $3.5 million over five years by reducing our
server hardware by more than 90 percent. However, the cost savings will likely be greater due to
additional benefits, like the increased compute capacity we can get using AWS. That lets us continually
add more and larger workloads than we could using a traditional data center infrastructure, and
achieve savings by only paying for what we use.”
Delaware North moved almost all of its applications to AWS, including enterprise software such as its
Fiorano middleware, Crystal Reports and QLIK business intelligence solutions, its Citrix virtual desktop
system, and Microsoft System Center Configuration Manager, which is used to manage workstations.

The most dramatic physical change was the elimination of 205 servers. Everything running
on that hardware was migrated to AWS. The IT department decided to keep about 20 servers
on-premises at the new headquarters building to run communications and file-and-print
tasks.
“We erred on the side of caution to ensure there is no latency with these tasks, but once we
reach a certain comfort level, we may move these to the cloud as well,” says Brian Mercer,
Senior Software Architect for the project.

Six months into its cloud migration, Delaware North was realizing benefits in addition to its
data center consolidation, including cost-effective security compliance, enhanced disaster
recovery, and faster deployment times for new services.
“Robust security in a retail environment is critical for us because of our many retail
operations, and AWS is enormously helpful for that,” says Brian Mercer, the senior software
architect for the project. “By leveraging the security best practices of AWS, we’ve been able
to eliminate a lot of compliance tasks that in the past took up valuable time and money.”
He adds that the company also has increased its disaster recovery capabilities at a lower cost
than what was available in its previous data center deployment. “It significantly improved our
business continuity capabilities, including seamless failovers,” he says.
The solution is also helping Delaware North operate with greater speed and agility. For
example, it can bring in new businesses - either through contracts or acquisitions - and get
them online much faster than in the past by eliminating the need for traditional IT
procurement and provisioning. It used to take between two and three weeks to provision
new business units; now it takes one day. The Delaware North IT team is also using AWS to
overhaul its operations by eliminating outdated and cumbersome processes, cleaning up
documentation, and leveraging the benefits of running test and development tasks in

combination with rapid deployment of services through the cloud.
“Our DevOps team can now spin up the resources to push out a service in just minutes,
compared to the weeks it used to take,” says Brian Mercer. “With AWS, we can respond
much faster to business needs. And we can start repurposing time and resources to deliver
more value and services to our internal teams and to our customers.”

Module 1.3: AWS Infrastructure Overview

As we discussed earlier, AWS provides a broad set of services, such as compute power,
storage options, networking, and databases, delivered as an on-demand utility that is
available in seconds, with pay-as-you-go pricing. All of these services reside on the AWS
global infrastructure.
AWS’s global infrastructure can be broken down into three elements: Regions, Availability
Zones, and Edge Locations.
Let’s take a more in depth look at the AWS infrastructure and see what these are.

Module 1.3: AWS Infrastructure Overview

The foundation for the AWS infrastructure are the data centers. A data center is a location
where the actual physical data resides. AWS data centers are built in clusters in various global
regions.
Data centers are securely designed with several factors in mind.
Each location is carefully evaluated to mitigate environmental risk.
Data centers have a redundant design that anticipates and tolerates failure while maintaining
service levels.
To ensure availability, critical system components are backed up across multiple isolated
locations known as Availability Zones.
To ensure capacity, AWS continuously monitors service usage to deploy infrastructure to
support availability commitments and requirements.
Data center locations are not disclosed and all access to them is restricted.
In case of failure, automated processes move customer data traffic away from the affected
area.
A single data center typically houses 50,000 to 80,000 physical servers, as larger data centers
are undesirable.

All data centers are online and serving customers, so no data center is “cold.”
AWS utilizes custom, multi-ODM sourced network equipment. Original Design Manufacturer
(or ODM) designs and manufactures products based on specifications from a second
company. The second company then rebrands the products for sale.

Module 1.3: AWS Infrastructure Overview

The AWS Cloud infrastructure is built around Regions and Availability Zones.

An AWS Region is a physical geographical location in the world where we have multiple
Availability Zones. To achieve fault tolerance and stability, Regions are isolated from one
another. Resources in one region are not automatically replicated to other regions. Each AWS
Region contains two or more Availability Zones. AWS has 18 regions worldwide.
When you store data in a specific region, it is not replicated outside that region. AWS never
moves your data out of the region you put it in. It is your responsibility to replicate data
across regions, if your business needs require that. AWS provides information about the
country, and, where applicable, the state where each region resides. You are responsible for
selecting the region to store data in, based on your compliance and network latency
requirements. When you distribute applications across multiple Availability Zones, be aware
of location-dependent privacy and compliance requirements, such as the EU Data Privacy
Directive. When selecting a Region, it is also important to consider which region will help you
optimize latency while minimizing costs and adhering to whatever regulatory requirements
you may have.
Let’s dive deeper on this point. If you are leveraging cloud computing services, you can easily
deploy your application in multiple regions. For instance, you can have an application in a

region nearest your headquarters, such as San Diego, and then also have a deployable
application in a region in the East Coast. Let’s say your largest customer base is located in
Virginia. With a few clicks, you can easily deploy in the US East region to provide a better
experience for your customers located there. You will be minimizing latency and increasing
agility for your organization within minutes and with minimal cost.

AWS products and services are available by region, so you may not see all regions available
for a given service. AWS is steadily expanding its global infrastructure to help customers
achieve lower latency and higher throughput, and to ensure that your data resides only in the
Region you specify.
The AWS Cloud has announced plans to expand with 17 new Availability Zones in four new
geographic Regions: Bahrain, Hong Kong, Sweden, and a second AWS GovCloud Region in the
Eastern US.
The isolated GovCloud (US) Region is designed to allow US government agencies and
customers to move sensitive workloads into the cloud by addressing their specific regulatory
and compliance requirements.

Module 1.3: AWS Infrastructure Overview

Availability Zones consist of one or more discrete data centers designed for fault isolation,
each with redundant power, networking, and connectivity housed in separate facilities. They
are interconnected with other Availability Zones using high-speed private links. Some
Availability Zones have as many as six data centers; however, no data center can be part of
two Availability Zones.
Each Availability Zone is designed as an independent failure zone. This means that Availability
Zones are physically separated within a typical metropolitan region and are located in lowerrisk flood plains with specific flood-zone categorization that varies by region. In addition to
having a discrete uninterruptable power supply and onsite backup generation facilities, they
are each fed via different grids from independent utilities to further reduce single points of
failure. Availability Zones are all redundantly connected to multiple tier-1 transit providers.
Availability Zones in a region are connected through low-latency links.
You are responsible for selecting the Availability Zones where your systems will reside.
Systems can span across multiple Availability Zones. AWS recommends replicating across
Availability Zones for resiliency. You should design your systems to survive temporary or
prolonged failure of an Availability Zone if a disaster occurs. Distributing applications across
multiple Availability Zones allows them to remain resilient in most failure situations, including
natural disasters or system failures.

An Edge Location is where end users access AWS services.

It is a global network of 114 points of presence, with 103 Edge Locations and 11 regional
Edge Caches in 56 cities, across 24 countries. They are located in most of the major cities
around the world and serve requests for Amazon CloudFront and Amazon Route 53. Edge
Locations are currently located in North America, Europe, Asia, Australia, and South America.
AWS Edge locations offer CloudFront, Amazon Route 53, AWS Shield, and AWS Web
Application Firewall (or WAF) services.
CloudFront is a Content Delivery Network (or CDN) used to distribute content to end users to
reduce latency. Amazon Route 53 is a DNS service. Requests going to either one of these
services will be routed to the nearest Edge Location automatically.
Regional Edge Caches, used by default with Amazon CloudFront, are utilized when you have
content that is not accessed frequently enough to remain in an Edge Location. Regional Edge
Caches absorb this content and provide an alternative to that content having to be fetched
from the origin server.

Module 1.3: AWS Infrastructure Overview

The AWS Cloud infrastructure is built around Regions and Availability Zones. AWS Regions
provide multiple, physically separated, and isolated Availability Zones. An AWS Region
contains two or more Availability Zones.
An Availability Zone is a data center or collection of data centers that are connected with low
latency, high throughput, and highly redundant networking. Availability Zones are physically
distinct and each has equipment like Uninterruptible Power Supplies, cooling equipment,
backup generators, and security, to ensure uninterrupted operations.
This infrastructure has several valuable features:
• First, it is elastic and scalable. This means resources can dynamically adjust to increases or
decreases in capacity requirements. It can also rapidly adjust to accommodate growth.
• Second, this infrastructure is fault tolerant, which means it has built-in component
redundancy which enables it to continue operations despite a failed component.
• Finally, it requires minimal to no human intervention, while providing high availability with
minimal down time.

AWS offers a broad set of global cloud-based services that can be used as building blocks for
common cloud architectures. Some of the categories we will discuss in this module include
Compute, Storage, Database, Networking & Content Delivery and Security, Identity &
Compliance.
If you go to the AWS front page, aws.amazon.com, and scroll down to find the section that
allows you to explore the products. It places all of the products and services into different
categories. For example, click on Compute and you will see Amazon EC2 is first on the list.
There are also a lot of other products and services that appear in the compute category.
If you click Amazon EC2, it brings you to the Amazon EC2 main page. Select the link to review.
It gives you a detailed description of the product and lists some of the benefits. Additionally,
there are links for Product Details, Instance Types, Pricing, Getting Started, FAQs, and
Resources. When you click on Product Details there is more detailed information about
Amazon EC2.
Explore the different service groups to understand the categories and services within them.
Now that you know how to locate information about different services, let’s narrow our
discussion to the AWS Core Services.
