Best Cluster Strategy for On-Premises Servers with ECS Anywhere

I'd definitely recommend setting up one cluster per location. ECS Anywhere treats clusters as shared management spaces, so if you put all your locations into a single cluster, it increases the risk of something negatively impacting multiple sites all at once. Isolating them by location helps maintain separate failure domains and keeps things easier to manage during local outages. Sure, more clusters means more to manage, but automating that can really help with operations.

Imagine you have a separate manager for each store. That's what managing 200 clusters is like—very safe but maybe a bit tedious. Alternatively, one big cluster is like having just one manager for all stores; if that manager goes down, it affects all of them. A middle-ground approach would be to cluster them into 'districts' with 10 clusters for 20 sites each. This could strike a balance between manageability and safety.

One K8s cluster could work, but considering your failover requirements, I think staying isolated at each location would be smarter. You’d want to avoid adding layers that cross those isolated sites.”},{
