ONE HUB, 34 CLUSTERS: LESSONS FROM A GITOPS CONTROL PLANE AT SCALE

Summary from the TLDR DevOps newsletter

Nitish Mane describes an Argo CD hub that managed 34 clusters across 22 AWS accounts and one Oracle Cloud tenancy from a repository of 174 Helm charts. Per-cluster contracts, CI manifest diffs, and no-prune settings kept changes safe, and onboarding reportedly fell from 4 days to 1.7 hours.
