Security and latency
The downside of things like OpenSSH certificates, Kerberos, and SSL is that the connection setup time will take longer; so, in most cases, you'll want to establish a connection and hold it open before you actually need it. That way you aren't constantly handling the cost of setup and teardown. Although this approach is suitable for things like connecting to remote message queues and file servers, it can pose a problem if you need a large number of clients to connect to a large number of servers. In that case, you might want to investigate hardening the perimeter and removing authentication entirely to speed things up.
