summary
Migrated Adobe Experience Manager into a multi-tenant Kubernetes platform on Azure with a custom lifecycle operator that reconciles Flux, Argo Rollouts and security operators, running 37 clusters and ~17,000 environments across regions. Built sidecars and init containers for cache warm‑up, log/thread‑dump collection, Envoy tunneling and automated Log4j patching; use namespaces, quotas and Kata for tenant isolation. Calls out JVM ergonomics, CPU/memory request vs limit behavior, and estimates 15–25% cost savings from ARM nodes.
