summary
Karmada is a multicluster Kubernetes control plane that propagates configmaps, secrets and CRDs, provides cluster and application failover and an estimator-driven scheduler for spreading workloads. Bloomberg builds a managed service with a host cluster model and a stretch topology across multiple data centers using a central source-of-truth and sync operators. Contributions added support for air-gapped CRD fetch via custom HTTP source, custom CA certs, KMS plugin integration, configurable leaf cert lifetimes, external SCD clusters and extra volumes, and 36 public adopters with ~700 contributors.
