Serverless Architectures on AWS

There's a shift underway toward serverless cloud architectures. With the release of serverless compute technologies, such as AWS Lambda, developers are now building entirely serverless platforms at scale. In these new architectures, traditional back-end servers are replaced with cloud functions acting as discrete single-purpose services. By composing and combining these serverless cloud functions together in a loose orchestration, and adopting useful third-party services, you can build powerful yet easy to understand applications. Serverless architecture is about building rich, scalable, high-performing, and cost-effective systems without having to worry about traditional compute infrastructure, having more time to focus on code, and moving quickly.

Serverless Architectures on AWS teaches you how to build, secure and manage serverless architectures that can power the most demanding web and mobile apps. You'll get going quickly with this book's ready-made and real-world examples, code snippets, diagrams, and descriptions of architectures that can be readily applied. This book describes a traditional application and its back end concerns and then shows how to solve these same problems with a serverless approach. You'll begin with a high-level overview of what serverless is all about, start creating your own media transcoding system, and learn more about AWS. Next, you'll go in depth and learn about Lambda, API Gateway and other important serverless technologies. This section will teach you how to compose Lambda functions and discuss important considerations when it comes to building serverless systems. The third part of the book focuses on more advanced topics as your architecture grows. By the end, you'll be able to reason about serverless systems and be able to compose your own systems by applying these ideas and examples.
