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.

Summary

In this chapter, we have learned how security works in Lambda functions in a deep-dive mode. We have understood how VPCs and subnets work in the AWS environment. We have learned to create a VPC and also created public and private subnets. This will give you a better understanding of how security works from the whole of the AWS perspective.

We have also learned how to place your Lambda functions inside the VPCs and the subnets we have created throughout this chapter. We understood how to handle and route traffic inside our VPCs and subnets.

Finally, we also learned how to implement better security in our Python code using session-based access to other AWS components, thereby placing security in the control of the developer.

In the next chapter, you will learn about the Serverless Application Model (SAM) and how to write SAM models and deploy your Lambda applications through...
