Overview

Multi-cluster management allows you to use KCE in multi-cloud and hybrid-cloud scenarios. For example, you can use multi-cluster management to implement business backup and disaster recovery, high availability (HA) deployment, isolation of development and production environments, vendor lockin risk mitigation, cross-cluster compute resource scheduling, and cross-region nearest access. Kubernetes Federation V2 (KubeFed) allows you to orchestrate configurations of multiple member clusters by using the API defined in the host cluster, and centrally manage the Kubernetes clusters in federated mode.

The multi-cluster management feature of KCE supports a variety of cluster types and sources. After you import third-party clusters, including clusters of customers and Kubernetes clusters of other public cloud vendors, you can create cluster federations of selected managed clusters, dedicated clusters, and third-party clusters. Federation management is supported in the CN North 1(Beijing), CN East 1(Shanghai), and CN South 1(Guangzhou) regions, meeting your business requirements for cross-region deployment.

Terms

Federation: a collection of clusters, including one host cluster and multiple member clusters. The host cluster communicates with the member clusters over the Internet, and the networks of the member clusters can be completely isolated from each other.

Host cluster: the cluster that provides the KubeFed API and control plane. The cluster can also be used as a member cluster to deploy federated resources.

Member cluster: a cluster that joins the federation by using the KubeFed API. Member clusters are managed by the host cluster. Federated resources are automatically synchronized among the member clusters after the resources are deployed.
