You can use the Autoscaler APIs to set up cross-cluster load-balancing in your SDDC.

In an SDDC with multiple clusters, cross-cluster load balancing can prevent individual clusters from becoming overloaded and triggering unnecessary scale-out events. Cross-cluster load-balancing enables Elastic DRS to balance load across all the clusters in your SDDC, not just within a single cluster. For more information, see the Autoscaler API reference.
