+## Why federation
+
+Federation makes it easy to manage multiple clusters. It does so by providing 2
+major building blocks:
+
+  * Sync resources across clusters: Federation provides the ability to keep
+    resources in multiple clusters in sync. This can be used, for example, to
+    ensure that the same deployment exists in multiple clusters.
+  * Cross cluster discovery: It provides the ability to auto-configure DNS
+    servers and load balancers with backends from all clusters. This can be used,
+    for example, to ensure that a global VIP or DNS record can be used to access
+    backends from multiple clusters.
+
+Some other use cases that federation enables are:
+
+* High Availability: By spreading load across clusters and auto configuring DNS
+  servers and load balancers, federation minimises the impact of cluster
+  failure.
+* Avoiding provider lock-in: By making it easier to migrate applications across
+  clusters, federation prevents cluster provider lock-in.
+
+
+Federation is not helpful unless you have multiple clusters. Some of the reasons
+why you might want multiple clusters are:
+
+* Low latency: Having clusters in multiple regions minimises latency by serving
+  users from the cluster that is closest to them.
+* Fault isolation: It might be better to have multiple small clusters rather
+  than a single large  cluster for fault isolation (for example: multiple
+  clusters in different availability zones of a cloud provider).
+  [Multi cluster guide](/docs/admin/multi-cluster) has more details on this.
+* Scalability: There are scalability limits to a single kubernetes cluster (this
+  should not be the case for most users. For more details:
+  https://github.com/kubernetes/community/blob/master/sig-scalability/goals.md).
+* Hybrid cloud: You can have multiple clusters on different cloud providers or
+  on-premises data centers.
+
+
+### Caveats
+
+While there are a lot of attractive use cases for federation, there are also
+some caveats.
+
+* Increased network bandwidth and cost: The dederation control plane watches all
+  clusters to ensure that the current state is as expected. This can lead to
+  significant network cost if the clusters are running in different regions on
+  a cloud provider or on different cloud providers.
+* Reduced cross cluster isolation: A bug in the federation control plane can
+  impact all clusters. This is mitigated by keeping the logic in federation
+  control plane to a minimum. It mostly delegates to the control plane in
+  kubernetes clusters whenever it can. The design and implementation also errs
+  on the side of safety and avoiding multicluster outage.
+* Maturity: The federation project is relatively new and is not very mature.
+  Not all resources are available and many are still alpha. [Issue
+  38893](https://github.com/kubernetes/kubernetes/issues/38893) ennumerates
+  known issues with the system that the team is busy solving.
