💡How Cloud-Native Architecture works
  • 1Cloud-Native Architecture primarily controls cloud Kubernetes platform.
  • 2Cloud-Native Architecture uses the Kubernetes mechanism of Cloud-Native Architecture applies cloud Kubernetes platform to connect cluster workloads to cloud identity, networking, storage, and scaling.
  • 3The API server records and validates the objects declared for Cloud-Native Architecture.

💡Cloud-Native Architecture workflow
  • 1Identify the exact workload, namespace, identity, traffic, storage, or cluster boundary affected by Cloud-Native Architecture.
  • 2Create only the manifest or command required for Cloud-Native Architecture instead of combining unrelated changes.
  • 3Apply Cloud-Native Architecture in a disposable environment and watch resource status rather than treating command success as completion.
  • 4Record the expected result, rollback method, and cleanup command for this Cloud-Native Architecture exercise.
💡Verify Cloud-Native Architecture
