Karmada
Karmada is a CNCF sandbox project that focuses on deploying and running workloads across multiple Kubernetes clusters. Its claim to fame is that you don’t need to make changes to your application configuration. While CAPI was focused on the lifecycle management of clusters, Karmada picks up when you already have a set of Kubernetes clusters and you want to deploy workloads across all of them.

It can work with Kubernetes in the cloud, on-prem, and on the edge.

- Karmada controller manager
- Karmada scheduler
If you understand how Kubernetes works, then it is pretty...
