Mastering AWS Lambda

By: Yohan Wadia, Udita Gupta

Overview of this book

AWS is recognized as one of the biggest market leaders for cloud computing and why not? It has evolved a lot since the time it started out by providing just basic services such as EC2 and S3 and today; they go all the way from IoT to Machine Learning, Image recognition, Chatbot Frameworks, and much more! One of those recent services that is also gaining a lot of traction is AWS Lambda! Although seemingly simple and easy to use, Lambda is a highly effective and scalable compute service that provides developers with a powerful platform to design and develop Serverless event-driven systems and applications. The book begins with a high-level introduction into the world of Serverless computing and its advantages and use cases, followed by a deep dive into AWS Lambda! You’ll learn what services AWS Lambda provides to developers; how to design, write, and test Lambda functions; as well as monitor and troubleshoot them. The book is designed and accompanied with a vast variety of real-world examples, use cases, and code samples that will enable you to get started on your Serverless applications quickly. By the end of the book, you will have gained all the skills required to work with AWS Lambda services!

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!
