Karbon orchestrates Kubernetes clusters to simplify the provisioning and management of containerized applications. Kubernetes packages applications in their own dedicated containers together with all of the required operational components for running the application. Containers , which run inside of pods on top of nodes, are the core building block of Kubernetes architecture.


Using Karbon to manage Kubernetes operations requires a basic familiarity with key Kubernetes concepts.
