A New Era Of Application Services At Puppet Labs

Recently at Puppet Labs, we’ve been putting a lot of thought into how to make our server-side applications faster, smarter, and more modular. Today, we’re excited to give you a sneak peek into the future of some of this work.

Trapperkeeper is a new Clojure framework we’ve written for hosting long-running applications and services. It takes some of the lessons we’ve learned about high-performance server-side architecture over the last few years and combines them with patterns for maximizing modular, reusable code. It’s entirely open source, and we’re looking forward to seeing how the community helps it grow and evolve.

We’ve actually been thinking about this for a few years; the fruits of our original efforts became available in the form of PuppetDB, originally released in May of 2012. PuppetDB has been an overwhelming success for us, so since that time, in addition to improving PuppetDB itself, we’ve been thinking about how to take some of the technology choices from the project, and take advantage of them elsewhere in the Puppet ecosystem. Let’s take a quick dive into some of those technology choices...
