Mastering AWS Lambda

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!

Packaging and deploying

We touched on the concept of packaging and deploying a simple Lambda function earlier in Chapter 1, Introducing AWS Lambda and parts of it in this chapter as well, however in this section, we will be doing things a bit differently! Rather than covering the steps all over again, we will be exploring a few simple and powerful open source Lambda deployment tools that are currently out there in the market today! Why tools you ask? Well, why not?

As a developer we always want to make the deployment and management of our codes simpler and hassle free, especially when it comes to working with a lot of Lambda projects at the same time. These tools accelerate time to development and also help us reduce any errors that may occur when working with the AWS Management Console or the AWS CLI. In this section we will be exploring two such tools that are gaining a lot...
