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.

Security best practices

Ensuring high-level security has always been a major problem for microservices. There are multiple levels of software that you need to keep in mind while designing the security layers. The engineers need to define the security protocols for each of the services and then also define the protocols for the data interaction and transfer between each service.

You have to keep all these aspects in mind before architecting distributed serverless systems, where (almost) each Ansible task is a microservice. In this section, we will understand how to architect the security protocols, and also monitor them using some of AWS's built-in services.

We will go through a step-by-step understanding of how to write security protocols for our serverless architectures:

  1. Firstly, whenever you are creating a session inside your AWS Python scripts using Boto, try to create...
