Verify vRealize Automation Components Are Highly Available

Verify that you can continue to operate the vRealize Automation stack even as individual stack components become unavailable.

Performing system login and provisioning blueprints while some of the stack components are unavailable validates that the vRealize Automation stack is built for resiliency and eliminates single points of failure.

Expected Outcome
You can successfully perform all the login and provisioning operations without any disruptions.
