Serverless Architectures on AWS, Second Edition teaches you how to design, secure and manage serverless backends that can power the most demanding web and mobile apps! This new edition has been fully-updated to include new chapters on current best practices and innovative use-cases, along with full coverage of the latest changes to AWS.

About the Technology

Leave behind tedious server maintenance, scheduled downtimes, constant patching, and complex infrastructure! Serverless technologies such as AWS Lambda, give you the tools to build complete applications at scale using self-managing cloud-hosted services that automatically update and scale on demand. Serverless systems enable flexible new architectures that replace or augment traditional back-end servers. On the AWS platform, the centerpiece of serverless applications is AWS Lambda, a service for writing and deploying small, single-purpose cloud-hosted functions. By composing and combining Lambda functions together with other AWS and third-party services, you can create powerful applications that help bring down costs, work faster, and have fantastic support.

About the book

Serverless Architectures on AWS, Second Edition teaches you how to design, secure, and manage serverless backend APIs for web and mobile applications on the AWS platform. You'll get going quickly with this book's relevant real-world examples, code listings, diagrams, and clearly-described architectures that you can readily apply to your own work. You’ll master serverless systems using AWS Lambda and the myriad of other services on the AWS platform.

This new edition has been fully updated to reflect the newest serverless design best practices and changes to AWS, including covering DynamoDB, Cognito, Google Firestore, AWS Elementals MediaConvert, Step Functions, and much more. There are also three new chapters dedicated to black belt tricks for Lambda, using patterns, and even DevOps for serverless applications.
