Overview of this book

With the growing interest in Software Defined Data Centers (SDDC), vRealize Automation offers data center users an organized service catalog and governance for administrators. This way, end users gain autonomy while the IT department stays in control, making sure security and compliance requirements are met. Learning what each component does and how they dovetail with each other will bolster your understanding of vRealize Automation. The book starts off with an introduction to the distributed architecture that has been tested and installed in large scale deployments. Implementing and configuring distributed architecture with custom certificates is unarguably a demanding task, and it will be covered next. After this, we will progress with the installation. A vRealize Automation blueprint can be prepared in multiple ways; we will focus solely on vSphere endpoint blueprint. After this, we will discuss the high availability configuration via NSX loadbalancer for vRealize Orchestrator. Finally, we end with Advanced Service Designer, which provides service architects with the ability to create advanced services and publish them as catalog items.

Chapter 6. Testing Failover Scenarios for vRealize Automation Components

Firstly, I want you relax as we have completed the most composite portion of the installation. However, the job is not yet done. As you can imagine, a failover can have multiple meanings in the world of IT. I would like to elucidate this before we go forward; here, failover refers to the process of promoting the passive node to an active node in a event where the active node fails.

Having meticulously designed the high availability for all the components in vRealize Automation, it's imperative that we comprehend the technicalities around it:

  • Understanding the HA mode for all components in vRealize Automation

  • Identifying active nodes in the current state

  • How to identify whether the active component failed

  • How to promote a passive component in the event the active component fails

The following topics will be covered in this chapter:

  • Failover of vPostgres

  • Failover of vRA CAFÉ appliances

  • Failover of Model Manager Web

  • Failover of...
