The vRealize Automation virtual appliance includes the cloud management Web portal, an embedded vRealize Orchestrator instance and database services. The vRealize Automation portal allows self-service provisioning and management of cloud services, as well as authoring blueprints, administration, and governance. The vRealize Automation virtual appliance uses an embedded PostgreSQL database for catalog persistence and database replication.

Design Decision

Design Justification

Design Implication

CSDDC-CMP-004

Deploy a single instance of the vRealize Automation appliance.

A single instance provides full provisioning capabilities for the consolidated cluster while maintaining a minimal footprint.

Relies on vSphere HA for application availability and there is no vRA embedded Postgres replication in this design.

CSDDC-CMP-005

During deployment, configure the vRealize Automation appliance with 18 GB vRAM.

Supports deployment of vRealize Automation in environments with up to 25,000 Active Directory users.

For environments with more than 25,000 Active Directory users of vRealize Automation, vRAM must be increased to 22 GB.
