Building Serverless Applications with Python

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.

Setting Up Serverless Architectures

So far, we have understood what the serverless paradigm is, and also how serverless systems work. We have also understood how AWS Lambda's serverless tool works. We have also learned the basics of how triggers work in AWS Lambda as well as a detailed understanding of the system settings and configuration available to the user in the Lambda environment. We have also learned how the Lambda console works, and also how to identify and use various parts of the Lambda console in detail, including code deployment, trigger manipulation, deploying tests in the console, versioning our Lambda function, and also the different settings available.

By the end of this chapter, you will have a clear understanding of all the important triggers available for AWS Lambda and how you can use them to set up efficient Lambda architectures. You will also understand...
