Distributed Systems talk at BarCamp Portland 6

This was put together rather quickly while learning how to use Keynote for the first time.

Transcript

1. DISTRIBUTED SYSTEMS WITH PUB/SUB or how micro services can rock your socks
2. It’s actually quite simple You have two processes You send a message from one to the other Surprise! Distributed system.
3. Why would I bother?! Separation of concerns. More robust in the face of nodes failing. Easier to bring up and take down nodes.
4. Ok but what are WE doing? We have an IRC bot. It listens to and writes to a couple Pub/Sub channels. This lets us do our logic in other processes.
5. The real fun. They don’t have to be on the same server.
