HTTP/2, the new version of the HTTP protocol, provides a lot of new features for server-to-server communication:
* bidirectional communication using push requests
* multiplexing within a single TCP connection
* long running connections
* stateful connections
This talk shows HTTP/2's potential for new server-to-server APIs.
