Exploring the Serverless Framework

In the previous chapter, we learned how to use the AWS Management Console to create Lambda functions and APIs. Now, we will use the Serverless framework to programmatically create APIs and Lambda functions. We will use the serverless command-line interface to deploy and test our functions. This will tremendously speed up our development processes.

The term serverless generally refers to applications that make heavy use of third-party cloud services, such as AWS Lambda. These services are also sometimes referred to as cloud functions, serverless microservices, or serverless functions. This doesn't mean that there are no servers involved anymore, just that you haven't installed to manage and operate these servers yourself. This is handled by the cloud provider, who takes care of things like scalability, high availability, security, performance...

Key benefits

Learn to write, run, and deploy Lambda functions in the AWS cloud

Make the most of AWS Lambda functions to build scalable and cost-efficient systems

A practical guide to developing serverless services and applications in Node.js, Java, Python, and C#

Description

AWS Lambda is a part of AWS that lets you run your code without provisioning or managing servers. This enables you to deploy applications and backend services that operate with no upfront cost. This book gets you up to speed on how to build scalable systems and deploy serverless applications with AWS Lambda. The book starts with the fundamental concepts of AWS Lambda, and then teaches you how to combine your applications with other AWS services, such as AmazonAPI Gateway and DynamoDB. This book will also give a quick walk through on how to use the Serverless Framework to build larger applications that can structure code or autogenerate boilerplate code that can be used to get started quickly for increased productivity. Toward the end of the book, you will learn how to write, run, and test Lambda functions using Node.js, Java, Python, and C#.
