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.

Deploying for concurrent access


Until now, we were in the development stage and we could easily use the development server that comes packaged with Flask to quickly test our changes. But this development server is not a good choice if you are planning to run the application in production, and we need something more dedicated for that. This is because, in a production environment, we will be more concerned about the concurrency of the application, as well as its security aspects, like enabling SSL and providing more restricted access to some of the endpoints.

So, we need to figure out some choices here based on the fact that we need our application to handle a lot of concurrent accesses, while constantly maintaining a good response time for the users.

With this in mind, we end up with the following set of choices, which, by their nature are also fairly common in many production environments:

  • Application server: Gunicorn
  • Reverse Proxy: Nginx

Here, Gunicorn will be the application that will be responsible...
