I'm interested in peoples experiences with using VRA-cloud to manage a large number of Azure subscriptions and therefore Cloud Accounts. I have osme concerns around scalability. In our case we need to use well over a thousand Azure subscriptions.
What will help more than people's experience around this is the hard limit that is documented in vRA (Aria) documentation.
In any version of vRA > 8.8, for an XL clustered deployment we can have a maximum of 300 cloud accounts for Public Endpoints like AWS, Azure, and GCP.
Documentation link here - https://docs.vmware.com/en/vRealize-Automation/8.11/reference-architecture/GUID-9DD443EA-0F7A-43B3-A...
We are using VRA-SaaS and there is no limit documented, however I have heard from a colleague about some issues he ran into, around the 200 cloud accounts mark. More to do with the number of cloud zones if you have multiple regions in a azure subscription and a project will only support 100 cloud zones.
but I'm interested to hear about real world experiences
