The traditional approach to develop and run Java applications included setting up applications servers, required complex build and dependency management, and often relied on large enterprise frameworks. In contrast, serverless functions are ideally short-lived, single-purposed, and not reliant on extensive infrastructure configuration. This has encouraged new frameworks, concepts, and techniques to evolve. In this workshop, learn how to bring traditional Java Spring applications to AWS Lambda with minimal effort and iteratively apply optimizations to enhance your serverless Java experience. Hear about best practices, performance trade-offs, and design considerations for each step to help you make well-informed decisions when bringing enterprise Java applications to AWS Lambda.
