I’ve previously written some thoughts on service oriented architectures and since then I’ve wanted to explore beyond the currently accepted standard of sending and receiving JSON data over web APIs. Protocol Buffers With JSON there’s an overhead of transmitting plain-text over the wire coupled with parsing that text in your application once received. For many cases this is probably acceptable but for a large-scale distributed system this can represent a not insignificant cost in terms of bandwidth and computing resources.

One of the most bandied about buzzwords at the moment has got to be Docker. So many people I’ve spoken to claim to be moving their application environments to it and some even have it running in production with varying degrees of success. Fine in theory The theory of isolating groups of related processes into containers which then themselves can be further orchestrated to build out an environment is very appealing.
Some common pain points seem to keep cropping up time and time again as applications grow in size and complexity: tests get longer to run deployments become a much more involved process making a small fix to one area of code can often break something in another it can be much harder to reason about the system as a whole These large, monolithic applications are affectionately known as monorails in the Rails world and the common wisdom is to start splitting up the codebase into services: to extract areas of functionality out into self-contained, independent applications which work in unison to deliver the original capability.
Like a lot of people in technology a portion of my time is spent wondering what will be the next programming language, framework or whatever to take off and become popular. Of greater personal importance is the matter of which one of them will get added to my toolboox next and press-ganged into productive use. For years now Ruby has been my goto for a lot things and I’ve been doing more and more OS X and iOS development but it had been some time since I last picked up something new and I had a hankering for some shinyness.
