Find out the architecture Netflix (producers of such fine entertainment as "Lillyhammer" & "Arrested Development") is using for their next generation device metadata APIs – specifically, the tech stack & development+deployment processes. We will explore demonstrate real world use cases which make Scala stand out as a choice programming language for for building clean, beautiful, RESTful APIs with tools such as Swagger+Scalatra. Techniques will be demonstrated for producing & consuming JSON (json4s), as well as sending HTTP Requests (Dispatch), using MySQL & Cassandra, and Caching. We will also explore Scala testing frameworks, and how they plug into our larger CI/CD infrastructure, with additional discussions of Netflix OSS components.
