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!

So, yet another chapter comes to an end! We have come a small way from where we started off in the first chapter. By now, you should have understood and got a good feel of Lambda's true capabilities and potential as well! So, before we finish off this chapter, let us conclude by summarizing all that we have learned.

We started off by understanding what an event-based system is and how it actually works. Later we saw a few simple and easy to understand Lambda architecture patterns. Finally, we took a deep dive into how Lambda works with events with the help of event mappings and a few easy-to-replicate real world use cases as well.

In the next chapter, we will take the event mappings a step further by exploring few third party tools and services that can also trigger Lambda functions to perform some set of tasks. So, stay tuned for much more is coming your way!
