Crossplane is an open-source Kubernetes add-on that enables platform teams to assemble cloud infrastructure resources, without writing any code. Specifically, the SIG aims to find Kubernetes-native ways to: Expose workloads from multiple clusters to each other; Share cluster metadata and its place relative to others If multiple apps run in the same Kubernetes cluster, this means that these apps share the hardware, network, and operating system on the nodes of the cluster. What Is Multi-Cluster Kubernetes? A multi-cluster Kubernetes deployment is (as the term implies) one that consists of two or more clusters. Aug 20, 2024 · KubeFed (Kubernetes Federation): An official Kubernetes project that enables the management of multiple clusters from a single control plane. Import new config, add cluster, user, and context. It abstracts the complexities of Kubernetes, allowing developers to concentrate on coding rather than on operational intricacies. These clusters can be distributed across different data centers, regions, or cloud providers to ensure high availability, fault tolerance, and better performance. Concretely, two containers of two different apps running on the same node are technically two processes running on the same hardware and operating system kernel.
