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!

Processing content at the edge with Lambda@Edge

Lambda@Edge was launched by AWS during the 2016 AWS re:Invent summit; however, it had been in the preview mode until right now. The service basically allows you to execute Lambda functions in edge locations in response to CloudFront events. With this service, you now don't need to install, configure, or scale servers globally in order to customize your content. With Lambda@Edge, all this work is handled by the Lambda service itself. All you need to do is write the function and deploy it, and that's it!

At the time of writing, Lambda@Edge supports writing functions for the following CloudFront events:

  • Viewer request: When CloudFront receives a request from a viewer
  • Viewer response: Before CloudFront returns the response to the viewer
  • Origin request: Before CloudFront forwards a request to the origin
  • Origin response: When...
