Overview of this book

Serverless architectures allow you to build and run applications and services without having to manage the infrastructure. Many companies have adopted this architecture to save cost and improve scalability. This book will help you design serverless architectures for your applications with AWS and Python. The book is divided into three modules. The first module explains the fundamentals of serverless architecture and how AWS lambda functions work. In the next module, you will learn to build, release, and deploy your application to production. You will also learn to log and test your application. In the third module, we will take you through advanced topics such as building a serverless API for your application. You will also learn to troubleshoot and monitor your app and master AWS lambda programming concepts with API references. Moving on, you will also learn how to scale up serverless applications and handle distributed serverless systems in production. By the end of the book, you will be equipped with the knowledge required to build scalable and cost-efficient Python applications with a serverless framework.

Versioning Lambda functions

The concept of the Version Control System (VCS) is for controlling and managing versions of code. This functionality is available directly from the main Lambda console. Let's try and learn how to version our Lambda functions:

  1. The first option in the Actions drop-down in the Lambda console is the Publish new version option. This option can be seen here:
  1. When the Publish new version option is selected, the versioning popup of the Lambda console would be seen on the console. This would ask about the name for the new version of your Lambda function. The popup looks something like this:
  1. After clicking the Publish button, you will be re-directed to the main Lambda console. The successfully created Lambda version in the console looks something like this:
  1. In the bottom half of the page, the following message can be noticed: Code and handler editing...
