Serverless architecture is about having more time to focus on code, and

moving quickly. In these new architectures, traditional back-end

servers are replaced with cloud functions acting as discrete singlepurpose

services. With serverless compute technologies like AWS

Lambda, developers can build entirely serverless platforms at scale.

manage serverless architectures that can power the most demanding

web and mobile apps. This book has many ready-made and real-world

examples, code snippets, diagrams, and descriptions of architectures

that can be readily applied. It describes a traditional application and its

back end concerns and then shows how to solve these same problems

with a serverless approach. By the end, readers will be able to reason

about serverless systems and be able to compose their own systems by

applying these ideas and examples.

• Up-to-date with the most current platform trends

• Real-world examples, code snippets, and diagrams

This book is for all software developers interested in back end technologies.

Experience with JavaScript (node.js) and AWS is useful but not required.

Lambda is a compute service that executes code written in JavaScript

(node.js), Python, or Java on AWS infrastructure. Source code is deployed

to an isolated container that has its own allocation of memory, disk space,

and CPU. Serverless architectures herald a new way of building scalable,

powerful, cost-effective, and high-performing back end systems. They

encourage a new way of creating applications through the use of a stateless

compute service to execute code.
