The siren song of Serverless lures developers in with promises of “only write business logic” and “deliver value quickly”, but it’s often unclear how to actually work on large-scale, real world Serverless applications, especially in an old-school language like Java. Concerns like incremental builds, configuration management, and continuous delivery are incredibly important. More so than the actual underlying technology, how these process concerns are addressed determines whether your team truly realizes the benefits of a Serverless architecture.
In this talk, Symphonia co-founder John Chapin builds on the themes of his QCon 2017 talk, “Fearless AWS Lambdas”, and describes the nuts and bolts of building large-scale Serverless applications using Java. He walks through the efficacy of a Java approach to a variety of Serverless use cases, and through live examples demonstrates pragmatic approaches to developing scalable, evolvable, multi-Lambda applications.
