Crossplane Kubernetes Control

Crossplane is a framework that extends Kubernetes to manage infrastructure across clouds (AWS, Azure, GCP) as Kubernetes resources. Instead of Terraform, you define a managed resource in YAML: kind: RDSInstance, name: mydb, class: postgres. Crossplane watches for this resource, creates the RDS instance, and syncs status back to Kubernetes. Key concepts: Managed Resources (cloud resources exposed as K8s objects), Providers (AWS, Azure, GCP connectors), Compositions (templates combining resources), Claims (user-friendly abstractions).
