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 9. Profiling Applications for Performance

Over the course of this book, we have seen how much the performance and scalability of an application matters inside an enterprise environment; with this in mind, we dedicated a significant portion of the book to understanding how to build an application that is not only performant but is also scalable.

So far, we have just seen some best practices for what we can do to build a performant and scalable application, but not how to figure out whether a particular piece of code in our application is slow and what might be causing it.

For any enterprise-grade application, improving its performance and scalability is an ongoing process, as the user base of the application keeps growing and the application's functionality continues to get more and more sophisticated. All of this effort requires an understanding of what is going on inside the application and on which parts of the application we need to focus for possible optimizations that can give...
