Kubernetes provides great primitives for deploying applications to a cluster: it can be as simple as `kubectl create -f app.yaml`. Deploy apps across multiple clusters has never been that simple. How should app workloads be distributed? Should the app resources be replicated into all clusters, replicated into selected clusters, or partitioned into clusters? How is access to the clusters managed? What happens if some of the resources that a user wants to distribute pre-exist, in some or all of the clusters, in some form?
In SIG Multicluster, our journey has revealed that there are multiple possible models to solve these problems and there probably is no single best-fit, all-scenario solution. [Federation](https://kubernetes.io/docs/concepts/cluster-administration/federation/), however, is the single biggest Kubernetes open source sub-project, and has seen the maximum interest and contribution from the community in this problem space. The project initially reused the Kubernetes API to do away with any added usage complexity for an existing Kubernetes user. This approach was not viable, because of the problems summarised below:

The project initially reused the Kubernetes API to do away with any added usage complexity for an existing Kubernetes user. This approach was not viable, because of the problems summarised below:
* Difficulties in re-implementing the Kubernetes API at the cluster level, as federation-specific extensions were stored in annotations.
* Limited flexibility in federated types, placement and reconciliation, due to 1:1 emulation of the Kubernetes API.
