To configure the consumption portal for your SDDC on VMware Cloud on AWS implementation as Region C in this design, you can configure the on-premises vRealize Automation system.
You can use your on-premises vRealize Automation system with your SDDC on VMware Cloud on AWS as a deployment target end point. With this configuration, you can reuse the templates and blueprints that you developed for the on-premises environment, reducing the time required to stand up an additional environment.
Note: Some blueprints might require a reconfiguration.
