Over the past 4 years, the production architecture at the Gilt Groupe has evolved from a single monolithic web application to a highly-distributed collection of more than 200 micro-services and small web applications. This architectural shift allows greater scalability and faster, less coupled development of new features, but also presents challenges around maintaining consistent development, testing, and deployment processes. We've developed a number of techniques for addressing these challenges and implementing new features using our preferred language of Scala. This experience report will discuss some of the interesting and novel ways we make use of Scala including: Creating an SBT uber-plugin to abstract and unify the development process with testing, deployment, and operations Using the cake pattern to bridge the divide between unit testing and functional testing Type-safe shared configuration using Zookeeper Live inventory updates using Play WebSockets and Akka Actors.
