Cloud Controller Manager vs. Kubernetes Controller Manager
Cloud Controller Manager (CCM)
- Purpose: In its practice of utilizing the actual cloud-providing program, ‘Abstracts on-cloud operation’ outlines the petitioner’s relations with the cloud provider by naming its Kubernetes.
- Components: Some of the base controllers are the Node Controller, Route Controller, and Service controller, which are normally used.
- Focus: As per our explanation above, virtualization slicing applies to the instance level in the context of cloud resources (e.g., instances, load balancers, and routes).
Kubernetes Controller Manager
- Purpose: Keeps some of the necessary pods and services which may contain basic loops that are necessary for supporting the state of the Kubernetes cluster in their working condition.
- Components: They are predominantly made of the Node Controller, the Replication Controller, the End Point Controller, and the Service Account Controller.
- Focus: Fundamental maintenance of pods, Deployments, and services, among others; Basic management of pods, deployments, or services to ensure they are in the right state.
Key Differences
- The CCM is very specialized for the management of the cloud provider, as we have established while the Kubernetes Controller Manager is involved in generic operations such as the management of the computational resources for the Kubernetes cluster.
- The CCM assists Kubernetes in retaining the cloud-neutral technology by storing the code for cloud principles, while the Kubernetes Controller Manager deals with the working goal of Kubernetes functioning to maintain the specific status in the Kubernetes cluster.
The Role of Kubernetes Cloud Controller Manager
Container orchestration is currently established to be well recognized and has emerged as one of the fundamental uses of Kubernetes for carrying out clusters in the cloud. The Kubernetes Cloud Controller Manager (CCM) is a sub-component of Kubernetes and contributes to making contact with cloud providers closer, by connecting them. It does so by outlining and defining some of the major concepts and terms related to CCM and then going on to describe and explain in non-technical terms, with the help of illustrations and examples from the real world, how the CCM works.
