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!

Extending AWS Lambda with External Services

In the previous chapter, we learned how to leverage and execute few Lambda functions based on triggers. However, one key aspect of that chapter was that the events were generated by sources or services residing within AWS. But, what if the triggers are generated by an external service provider or a third-party tool? Is Lambda even capable of handling such external services and events? Well, that's exactly what we are going to discuss and talk about in this chapter!

In this chapter, we will be covering the following topics:

  • Understanding the concept of Webhooks and how they can be used to trigger Lambda functions remotely
  • Triggering Lambda functions with the help of a few commonly used third-party tools and services, such as Git, Teamwork, and Slack
  • Triggering Lambda functions from an external application
