Generally it depends on the capabilities of your different clusters and the underlying hardware.

As of recently, we performed limited scale testing on a very specific scenario:

  • A single machine hosted all clusters.
  • All clusters used KIND.
  • All clusters had 1 node only (control plane).
  • Not using globalnet.
  • Not using Lighthouse.

In these tests the maximum scale was ~30 clusters before Submariner became unstable.
As it was very limited scenario, the actual scale cap can be quite higher when using actual clusters.
