Messidge

(full documentation is on the web)

Messidge is a message passing framework for distributed systems needing a public gateway.

Messidge is basically client server rpc with a few differences. First, not only does it enforce authentication and encryption, but is able to guarantee the provenance of a particular message. Messages are routed to a traditional controller; synchronous, asynchronous and streaming replies are trivial; and are all multiplexed over a single connection.

Having a background in containers, Messidge also has a concept of nodes - being services provided across a private LAN (or VPC) that can be announced as part of a resource offer when the client connects. There are no 'addresses' as such and these services are provided transparently as if they are part of the server.

The details...

  • User connections are through asymmetric keys (via libnacl).
  • Includes a lightweight invite/confirm server for client accounts.
  • Handles session management for client connections.
  • Automatic fail/reconnect with event callbacks.
  • ...so any component can be restarted with no ill effects.
  • ZeroMQ, cbor and multiprocessed encryption.

Above all it's simple, fast, and well suited to agile development.
