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!

Build and Deploy Serverless Applications with AWS Lambda

In the previous chapter, we saw how easy it is to build and integrate your applications and third party services with AWS Lambda functions. In this chapter, we will be taking things up a notch by learning how to design and build simple serverless applications with Lambda and a few other AWS services in the form of Serverless Application Model (SAM) and a newly launched service called as Step Functions.

In this chapter we will be learning:

  • What the SAM template is and how to build serverless applications with it
  • Using SAM to build and deploy serverless applications using simple examples
  • Introducing AWS step functions
  • Building coordinated Lambda services using step function's visual workflows

So without any further delays, let's get started!
