How to scale GitOps in the enterprise: From single cluster to fleet management

Implementing GitOps at scale can lead to challenges such as config sprawl, Git repository bottlenecks, and cultural resistance. State store strategies like OCI registries, ConfigHub, and multi-cluster topology patterns are key to overcoming these obstacles. Secrets management through Sealed Secrets and External Secrets Operator, policy enforcement with Kyverno, multi-tenancy via Argo CD Projects, and repository organization with trunk-based development and progressive delivery strategies are vital components of scaling GitOps. Choosing the right tool, whether it's Argo CD, Flux CD, or Sveltos, and building a central catalog for GitOps manifests are essential for managing large-scale GitOps deployments efficiently.
