Weave lets you run Kubernetes clusters anywhere without configuration changes.
Having deployed Kubernetes over Weave Net, you can rely 100% on cloud portability, thanks to Weave being an L2 network.
Additionally, thanks to Weave Run and how it handles IP address allocation as well as DNS without requiring a persistant store, you can deploy etcd over Weave as well.
Now you can simply configure all of the cluster components to have fixed DNS names, all you should care about is how these services are distributed accross your compute instances, e.g. what is the size of etcd cluster and whether it is on a dedcicated machines with the right type of storage attached.
You no longer have to care about the IP address of the API server or any of those things.
