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.

Failover of vPostgres


By now, we have understood that Postgres database follows the active-passive HA configuration with the manual failover process. This means that if the active node fails, the passive node can only be brought back online by manual steps. Postgres provides us with two choices (NSX load balancer and web-based) to identify which node is acting as a master or slave.

Choice 1 – identify active node via NSX load balancer

The first option is to do this via the NSX load balancer:

  1. Log in to vCenter Web Client and navigate to the Networking & Security tab.

  2. Click on NSX Edges and select the edge node where the load balancer service is enabled.

  3. Click the Pools option and click Show Pool Statistics (in this screenshot, both the CAFÉ nodes are active).

  4. Select the Postgres_Pool configuration, which lists the nodes and their statuses:

    Note

    If you recollect from Chapter 2, Distributed Installation Using Custom Certificates we added a passive (PG2) node and unchecked the Enable Member option...
