Hands-On Enterprise Application Development with Python

By: Saurabh Badhwar

Overview of this book

Dynamically typed languages like Python are continuously improving. With the addition of exciting new features and a wide selection of modern libraries and frameworks, Python has emerged as an ideal language for developing enterprise applications. Hands-On Enterprise Application Development with Python will show you how to build effective applications that are stable, secure, and easily scalable. The book is a detailed guide to building an end-to-end enterprise-grade application in Python. You will learn how to effectively implement Python features and design patterns that will positively impact your application lifecycle. The book also covers advanced concurrency techniques that will help you build a RESTful application with an optimized frontend. Given that security and stability are the foundation for an enterprise application, you’ll be trained on effective testing, performance analysis, and security practices, and understand how to embed them in your codebase during the initial phase. You’ll also be guided in how to move on from a monolithic architecture to one that is service oriented, leveraging microservices and serverless deployment techniques. By the end of the book, you will have become proficient at building efficient enterprise applications in Python.

Chapter 13. Going Serverless

As we have explored so far, Microservices offer a great alternative architecture with which we can approach the application development scenario. With the advantages of having faster release cycles, easy-to-launch new features and high scalability, the Microservices are a compelling choice for developers. But all of these Microservices still run in a server-based environment.

Running in a server-based environment is useful in terms of the response times of the applications because there is always a service that is ready to accept an incoming request. But there is one disadvantage: If there are no users, the applications keep on consuming system resources.

Recently, application developers have started to make a move toward a new approach of application development. This approach of development focuses on the applications being event-driven and launches an action based on the occurrence of some event. These kinds of applications are known as serverless applications...
