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.

Tracing requests inside microservices


Inside any application, a request may flow through several components before a final response for the request is generated. All of these components may do some processing that might be required on the process before they hand the request off to another component.

The tracing of a request allows us to visualize a rich amount of detail about the flow of a particular request. With the complete picture of the flow of the request, we can now work on finding out the places that may be causing a bottleneck in the performance of the request-response cycle, or figure out the components that may be causing the generation of an incorrect result.

Today, in the application development world, any serious application that runs on a large scale has one or another kind of tracing solution implemented into it so as to trace the flow of the requests inside the application. Currently, there are a huge number of tools and services that allow for enabling tracing inside the...
