The scalability and the concurrency limits outline the recommended maximums for a highly-available vRealize Automation cluster deployment.
Scalability and Concurrency
The following maximums are based on vRealize Automation 8.4. For more information on configuration limits, see the VMware Configuration Maximums.

Scale-up
With vRealize Suite Lifecycle Manager, you can perform scale-up operations on vRealize Automation, thereby increasing both scalability maximums and concurrency maximums for a vRealize Automation cluster.
With the scale-up capability, you can scale up to a higher-level profile, for example, you can scale up the vRealize Automation cluster from the medium profile to the extra large profile. As a result, each node in the vRealize Automation cluster increases the number of virtual CPUs and virtual memory to match the state of the higher profile.
