vRealize Code Stream shares a platform and some common services with vRealize Automation and is delivered in the same virtual appliance.
By entering the appropriate license keys, a System Administrator can unlock either vRealize Automation, vRealize Code Stream, or both products on the same appliance.
To install vRealize Code Stream only, you must:
Deploy and configure a vRealize Automation appliance
Apply vRealize Code Stream license
Configure a tenant to assign user roles in vRealize Code Stream
While vRealize Code Stream can be enabled on the same virtual appliance as vRealize Automation in lab or evaluation environments, it is not a recommended nor supported configuration for production systems, particularly when vRealize Automation is configured in High Availability (HA) mode. The current version of vRealize Code Stream does not support HA configuration and, if enabled on a vRealize Automation system in HA mode, can leave the overall system in an unpredictable state.
If you tried to enable vRealize Code Stream on a vRealize Automation system in HA mode, see the VMware knowledge base article at https://kb.vmware.com/kb/2145084 for the mitigation steps. If you have further questions, contact VMware Global Support Services.
