Most AWS Lambda books and introductions focus on Javascript and Python, but this book is written explicitly for Java developers who want to embrace the world of Serverless through AWS Lambda—without having to learn a new language on top of it. Serverless is a revolution in how we build and deploy software. It drastically reduces the complexity of building and operating applications, and reduces time-to-market and costs. AWS Lambda is Amazon’s Serverless "Functions-as-a-Service" platform, and is the core of most Serverless efforts ongoing today.
