 ## Introduction
-The AWS Cloud Map Multi-cluster Service Discovery Controller for Kubernetes (K8s) implements the Kubernetes [KEP-1645: Multi-Cluster Services API](https://github.com/kubernetes/enhancements/tree/master/keps/sig-multicluster/1645-multi-cluster-services-api) and [KEP-2149: ClusterId for ClusterSet identification](https://github.com/kubernetes/enhancements/tree/master/keps/sig-multicluster/2149-clusterid), which allows services to communicate across multiple clusters. The implementation relies on [AWS Cloud Map](https://aws.amazon.com/cloud-map/) for enabling cross-cluster service discovery. We have detailed [step-by-step setup guide](https://aws.github.io/aws-cloud-map-mcs-controller-for-k8s/)!

 - In deployment scenarios where participating clusters are provisioned into separate VPCs, connectivity will depend on correctly configured  [VPC Peering](https://docs.aws.amazon.com/vpc/latest/peering/create-vpc-peering-connection.html), [inter-VPC routing](https://docs.aws.amazon.com/vpc/latest/peering/vpc-peering-routing.html), and Security Group configuration. The [VPC Reachability Analyzer](https://docs.aws.amazon.com/vpc/latest/reachability/getting-started.html) can be used to test and validate end-end connectivity between worker nodes within each cluster.
 - Undefined behavior may occur if controllers are deployed without the required network connectivity between clusters.
