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!

Summary

Let's quickly recap the things we have learned in this chapter. For starters, we got to learn a bit about the birth of serverless computing along with few of its features, pros and cons. With the basics out of the way, we started our journey into the amazing world of AWS Lambda by understanding its nuances and how it works. We then explored the rich AWS Management Console and saw how easy and effortless it is to deploy a simple function. We even learnt how to package and invoke our functions using the AWS CLI as well. Towards the end of the chapter we learnt about how Lambda is priced along with few examples and what some of its limits are as well. Finally, we ended the chapter by exploring a quick comparison between the AWS compute services and learnt which service to use and when.

In the next chapter, we will be turning things up a notch by actually learning the anatomy of writing a Lambda function; its basic building blocks, how to log, and handle few common exceptions, as well as working with versioning and environment variables. So stick around, we are just getting started!
