Title:
Service Orientated Architecture to scale to infinity and beyond
or
Service Orientated Architecture for robust and scalable systems

Proposal:
Software Architecture is hard. And when your business grow, its getting even harder because scaling doesn’t come out the box and it’s not only the software which grows it’s also the team. So you have to find a way how to scale your software in a way that it stays easy maintainable for growing teams and scalable. I’d like to talk about Service Orientated Architecture in general and also share some experience and give some examples where SOA would save your ass and maybe places where SOA isn’t the best idea to implement.

# Schedule this to run once a day with cron. Doesn't matter what time since it parses yesterday's hits (by default).
# I only tested this on the Marco.org server, which runs CentOS (RHEL). No idea how it'll work on other distributions, but it's pretty basic.

Using CouchDB with node.js

First, get yourself a CouchDB! You can get a free hosted CouchDB in seconds or download a binary from the Couchio downloads page.

Next, install npm because all awesome node packages are in npm :)

Node has better support for HTTP than any language I've ever worked with and coincidentally CouchDB's interface is solely accessible via HTTP. First, let's just talk to CouchDB using an HTTP library and later we'll look at some higher level abstractions.
