What would high availability look like for the config server?
Consul is a cluster. Cassandra is highly available.
In aws would you run one per availability zone?

Just wanting to start a conversation, I know it doesn't need to be done for spring one.

The backend (for now at least) is git. The server itself is stateless so HA is trivial. So the question really comes down to whether there is an HA git repository (which we have chosen not to deal with explicitly in Spring Cloud). N.B. you only need the remote repository when a config server starts in a blank VM, so you can even tolerate outages of git server as well, as long as you don't scale up the config server while it is down.
