Learn AWS Serverless Computing

By: Scott Patterson

Overview of this book

Serverless computing is a way to run your code without having to provision or manage servers. Amazon Web Services provides serverless services that you can use to build and deploy cloud-native applications. Starting with the basics of AWS Lambda, this book takes you through combining Lambda with other services from AWS, such as Amazon API Gateway, Amazon DynamoDB, and Amazon Step Functions. You’ll learn how to write, run, and test Lambda functions using examples in Node.js, Java, Python, and C# before you move on to developing and deploying serverless APIs efficiently using the Serverless Framework. In the concluding chapters, you’ll discover tips and best practices for leveraging Serverless Framework to increase your development productivity. By the end of this book, you’ll have become well-versed in building, securing, and running serverless applications using Amazon API Gateway and AWS Lambda without having to manage any servers.

Event-Driven Applications

To help you understand why the serverless mindset is so important, it's key to know about the underlying principles in play. In the previous chapter, we learned a lot about how applications had influenced the way that data centers and infrastructures were put together. Now, we will dig further into these application patterns, particularly those surrounding integration and transferring data. Serverless allows applications to be truly reactive so that they can respond to their surroundings, their bounded context, and things that are happening within their wider ecosystem.

In this chapter, you will learn about the basis of event-driven applications, the importance they have in the industry, and how serverless has influenced the way they are built. Regardless of the architectures of the environments you're working in, having clear and efficient...
