Summary
AWS Lambda in Action is an example-driven tutorial that teaches you how to build applications that use an event-driven approach on the back end.
Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications.
About the Technology
With AWS Lambda, you write your code and upload it to the AWS cloud. AWS Lambda responds to the events triggered by your application or your users, and automatically manages the underlying computer resources for you. Back-end tasks like analyzing a new document or processing requests from a mobile app are easy to implement. Your application is divided into small functions, leading naturally to a reactive architecture and the adoption of microservices.
About the Book
AWS Lambda in Action is an example-driven tutorial that teaches you how to build applications that use an event-driven approach on the back-end. Starting with an overview of AWS Lambda, the book moves on to show you common examples and patterns that you can use to call Lambda functions from a web page or a mobile app. The second part of the book puts these smaller examples together to build larger applications. By the end, you'll be ready to create applications that take advantage of the high availability, security, performance, and scalability of AWS.

This is an excellent book for learning about not only AWS Lambda, but about other AWS services as well. That's because the author took the thorough approach of starting with foundational pieces -- by which I mean distributed and event-driven compute concepts, as well as select AWS micro-services used to implement them -- and wove a narrative that stitched them together into front-to-back working platform components. In my view, this is the correct approach because a similarly rigorous process is necessary when designing Serverless applications. And speaking of Serverless, you'll also gain perspective on the current direction that building I.T. functions and applications has taken. For readers who were never involved with the monolithic days of building applications and platforms, this perspective alone is valuable. The book is well-paced, extremely well-written and doesn't ask too much of the reader in terms of prior experience. AWS is gigantic these days (!), and continues to evolve rapidly; and this book presents a sweet-spot in between the (1) get-certified academic approach to AWS and (2) the practical, I need to get this going now demands. Highly recommended.
There is some real meat on this book. Having node.js and prior aws experience will be a big benefit to digesting the content. Unless you have built multiple lambda authentication services and been building lambda functions triggered off of dynamodb and s3 for some time, you will probably gain some knowledge from reading this book. If you are a complete aws newbie your mileage may vary and this book could be hard to digest. Ch9-11 guide you through building an authentication and media sharing app, with aws cognito, aws s3, aws lambda, and aws dynamodb working in concert. It is worth your time to read through the code which is printed in the book and understand and see how the parts are linked and working together. Unfortunately after chapter 12 the book content thins out and becomes more like a high level aws whitepaper.Cons:Aws api gateway deserves more screen time. I’m still confused about how it works especially method request/response and integration request/responseAws cloud formation did not get more screen time. Cloud formation could have had a nice supporting part in the action of ch9-11, it would have provided a aws standardized way of deployment been more informative. The author should mention node.js versioning issues that can gum up chapter 5 (see manning book forum)I’ll give 4 stars just to stand out. 4.5 is deserved but it’s not perfect.
An excellent guide that combines theory and practice really well to help get up to speed using Lambda quickly and responsibly. I also like the fact that all manning texts come with an ebook (pdf) so I don’t have to lug the physical copy around.
This is an excellent resource for getting started with serverless development .Prior to reading the book, I had the impression that AWS Lambda was just a one-trick-pony tool for building one-off utilities like automatic image thumbnail generation or adding small pieces of server-side glue code for mobile applications.In Chapter 1 my eyes were opened, as right from the beginning the book shows how you can create fully functional web and backend server equivalents just using the existing AWS services with Lambda to wire it all together with your own business logic.The author makes good use of diagrams to help visualize the flows between services throughout the book. The initial diagrams show how the interactions between AWS Events and Lambda functions can be chained together to create sophisticated flows. These flows are not that dissimilar to the flows you might already be familiar with from reactive programming styles.Chapter 2 quickly walks you through the process of building your obligatory Hello-World app and then subsequent chapters will progressively iterate to add more functionality, such as a web hooks and and security.The book assumes you don’t know very much about AWS beforehand and provides a basic introduction to some of the other related AWS services you’ll need in order to build non-trivial services. With over 80+ AWS services, no single book could ever possibly cover all of the AWS services you could might use with Lambda. Instead, this book concentrates on the services you are most likely to use with Lambda e.g IAM, Cognito, S3 etc.The book is divided into four main parts. Part 1 is a Getting Started guide. Part 2 is for Building and has a security theme (6 of the 8 chapters in this section are focused on security and authentication). Part 3 covers tools and strategies for Test, Deployment and Monitoring. Part 4 focuses on on integrations with external (non-AWS) services.Each of the chapters are quite dense with content, so it’s not something you can maybe read and walkthrough in a single lunchbreak. But the content is progressive, slowly building on the code you already know, so before you know it, you’ve got some reasonably comprehensive examples working. The examples provided are either in the NodeJS or Python languages, so a familiarity with either of those would be helpful but not essential. Each chapter ends with a well thought out exercise so you can hone your skills. This is a nice touch that I’d love to see in more books.The existing online documentation from Amazon on Lambda seems to concentrate mainly on either Reference-API themed pages or links to github examples. Both of these are certainly useful, but this book helps fill a void by actually showing you how to build up a Lambda based application from scratch and then secure it.If you’re considering using Lambda in a commercial enterprise, then this book will definitely help as it has lots of meaty examples and a strong focus on security throughout.
My Journey to Serverless technology started with AWS Lambda. I mostly learned about serverless reading online. As I started working more and more with Lambda I felt a need of something which I can refer quickly. This book makes a perfect reference guide for AWS Lambda. As the name suggest, it shows you the usage of AWS Lambda in "Action". It guides you very well through out the book with concepts and lots of examples.This book starts with an introduction to AWS Lambda and its concepts. Then it tells you how to write Lambda functions and test it. Then it gives you a big picture of how to use AWS Lambda to build event-driven applications, with various real world examples. Following that, it teaches you how to take your Lambda-based application from development to production. And finally, it ends with integrating AWS Lambda with external services.Great book overall. I will highly recommend this book to anyone who is looking to learn AWS Lambda with practical applications.
