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.

Summary

Well, there you have it. In this chapter, you learned about the fundamentals of how a Lambda function works in AWS. We covered quite a lot of thing: the permissions model, the three types of invocation, event source options, the code structure of a function, and what is available during execution. We also learned how to write, build, and deploy a function and, hopefully, you were successful in invoking your first Lambda function.

If you're developing and deploying solutions to AWS, it's really important that you learn how Lambda functions work and how to write your own. They will undoubtedly be a useful component in building future solutions.

In later chapters, we're going to explore a development life cycle for Lambda functions and explore some more advanced concepts. In the next chapter, we'll add another component that complements our Lambda compute...
