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.

Lambda’s metrics in CloudWatch

As we have learned and understood how the CloudWatch and the CloudTrail services work with respect to logging and monitoring, we shall move on to try and implement them for our Lambda function(s). In this section, you will learn about the types of metrics that Lambda possesses, which are monitored by CloudWatch, and how to create a dashboard with all those metrics.

Similar to previous sections in this chapter and book, we shall try and understand the concepts in the form of the following steps:

  1. When you navigate over to your AWS Lambda console, you will see the Lambda function which you have already created, in the list of available functions:
  1. When you click on the function, you will see two available options on the top: Configuration and Monitoring. Navigate to the Monitoring section. You will see a dashboard of metrics, which contains...
