Design low-maintenance systems using pre-built cloud services! Bring down costs, automate time-consuming ops tasks, and scale on demand.

In Serverless Architectures on AWS, Second Edition you will learn:

First steps with serverless computing
The principles of serverless design
Important patterns and architectures
How successfully companies have implemented serverless
Real-world architectures and their tradeoffs

Serverless Architectures on AWS, Second Edition teaches you how to design serverless systems. You'll discover the principles behind serverless architectures, and explore real-world case studies where companies used serverless architectures for their products. You won't just master the technical essentials-the book contains extensive coverage of balancing tradeoffs and making essential technical decisions. This new edition has been fully updated with new chapters covering current best practice, example architectures, and full coverage of the latest changes to AWS.

About the technology
Maintaining server hardware and software can cost a lot of time and money. Unlike traditional data center infrastructure, serverless architectures offload core tasks like data storage and hardware management to pre-built cloud services. Better yet, you can combine your own custom AWS Lambda functions with other serverless services to create features that automatically start and scale on demand, reduce hosting cost, and simplify maintenance.

About the book
In Serverless Architectures with AWS, Second Edition you'll learn how to design serverless systems using Lambda and other services on the AWS platform. You'll explore event-driven computing and discover how others have used serverless designs successfully. This new edition offers real-world use cases and practical insights from several large-scale serverless systems. Chapters on innovative serverless design patterns and architectures will help you become a complete cloud professional.

What's inside
