Part 2. Core Ideas

You’ve read through part 1 and now feel comfortable with some of the core concepts and principles of serverless architectures. It’s time to go deeper and look at authentication and authorization principles, as well as AWS Lambda and API Gateway, in more detail. In the next few chapters, you’ll write Lambda functions, configure a RESTful API, and even set up a website with user authentication. You’ll learn how quickly a single developer can put together a serverless back end and how powerful serverless technologies can be.
