AppViewX Overview
Application-oriented companies can only accomplish true business agility through the
automation of delivery infrastructure. At AppViewX, we believe that in order to power faster and
more compliant application provisioning, Network Operations groups need to work smarter, not
harder. Our platform offers a solid foundation to start your automation journey. It enables
complete change management automation by integrating with leading technology providers and
defining workflows for all stages of application provisioning on ADC: validation, approval,
implementation, and rollback. To get started, you can download Free AppViewX, which comes
with a series of preloaded application automation provisioning workflows.

Modify a Virtual Server Workflow Guide

Modify Virtual Server Workflow
With the Modify Virtual Server automation workflow, users can add or delete iRules, profiles,
monitors, and pool members on an existing virtual server. This workflow filters F5 ADC devices
based on the user’s access permissions, defined by Role Based Access Control (RBAC), and
displays the list of virtual servers available on the selected ADC device. When a virtual server is
selected, object details like iRules, profiles, monitors, and pool members are displayed in the
form fields. The workflow also provides an option to modify the association of these virtual
server objects and allows users to create change request tickets in ITSM systems like
ServiceNow for approvals and tracking. The service request change ID is associated with a
work order and is updated based on the implementation status.

The work order that is generated confirms the existence of the virtual server and its associated
objects before any changes are made. On successful pre-validation, the configuration changes
are reviewed through a two-level approval process: first by ServiceNow, then by AppViewX.
After approval is received, the configuration changes are implemented on the ADC device. A
post-validation script ensures the virtual server and the associated objects are modified
successfully.
