A talk about REST API architecture, the Scala language, the Netflix deployment platform and our own successful development model. Our REST API server project at Netflix was a big success, resulting in 150 web services in five months and no downtime. By taking advantage of self-documenting API frameworks, continuous integration with JSON-friendly API tests and automated deployments, we were able to focus on building services that would publicize themselves. This session highlights the engineering tools and processes that enable rapid API development, deployment and adoption. I'll cover the Scalatra, Swagger, and ScalaTest frameworks as well as Netflix's push-button deployment system using Jenkins and Asgard.
