Index

Chapter 15. Writing Lambda Functions

In the previous chapter, we understood serverless computing and took a quick look at how easy it is to get started with AWS Lambda functions using the AWS Management Console, as well as with the AWS CLI.

In this chapter, we are going to take things a step further by learning the anatomy of a typical Lambda function, and also how to actually write your own functions. The following topics are covered in this chapter:

Understanding the programming model for a Lambda function using simple functions as examples
Working with environment variables and versioning
Leveraging third-party tools for a quick and effortless code deployment to Lambda

So no more talking, let's get coding!
