Running Serverless
Running Serverless
Introduction to AWS Lambda and the Serverless Application Model
About the Book
This book will help you get started with AWS Lambda and the Serverless Application Model (SAM). Lambda is Amazon's engine for running event-driven functions, and SAM is an open-source toolkit that greatly simplifies configuring and deploying Lambda services. Together, they make it easy to create auto-scaling APIs and cloud services designed for serverless deployments. This book will help you:
- Design applications that get the most out of serverless architectures
- Create auto-scaling web APIs
- Handle background tasks and messaging workflows
- Set up a deployment pipeline for effective team collaboration
- Test and troubleshoot code designed for AWS Lambda
- Inspect and monitor serverless applications
This book is structured as a walk-through for building a practical application. We start from a simple static API and gradually grow it into an online image-resizing service, ready for millions of users, with all the supporting operational and infrastructural capabilities. The application closely resembles real-world systems that many of you will develop in your jobs. This will give you a good structure for your own work, and you will be able to almost copy parts to get a head start. As you discover how to create and deploy different parts of the application, you will also learn about key aspects of Lambda and related services, important tips, techniques and tools for running serverless.
The tutorial evolved from dozens of conference workshops and code camps. My colleagues and I have used the exercises from this book to teach hundreds of developers about serverless architectures, improving the examples through feedback into a great way to gradually introduce important concepts.
