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.

Service discovery in microservices


In traditional models of application development, the services pertaining to a particular application are usually deployed in a static manner where their network locations do not change automatically. If this is the case, then maintaining a configuration file that is updated occasionally to reflect the changed network location of the services is absolutely fine.

But in modern microservice-based applications—where the number of services may go up and down based on a number of factors, such as load balancing, upscaling, the launch of new features, and so on—maintaining a configuration file turns out to be a bit hard. In addition, most cloud environments these days do not offer static network deployments for these services, meaning that the network location for the services may keep on changing, adding more trouble to the maintenance of the configuration file.

 

To tackle these kinds of scenarios, we need to have something that is more dynamic and can adapt to...
