In AOS10, you configure per WLAN/SSID a cluster and optionally a secondary cluster in case the primary cluster is not available:

But you may consider a single cluster of 4 gateways which is active-active-active-active in that case. I don't think there is a active/standby mode anymore, unless you configure a single gateway as primary and another as secondary, but not sure in which case that would make sense.

Subject: AOS10 architecture - active/active?
We are planning for the move to AOS 10 from 8.
Hello,
We currently have a centralised cluster of several controllers (actually we have 2 active clusters and 2 standby clusters as we hit the max AP count limit). Two sets of Conductor & Standby Conductor. AOS 8.10.0.16
If we were to retain a centralised cluster model in AOS 10 (we haven't actually decided this yet, comments on this would be helpful too!) is it possible to have the active and standby clusters running in active/active mode - or is active/active only relevant to in-cluster redundancy? I know that the redundancy options are pretty much the same in general between AOS 8 and 10.
Many thanks,
Guy
