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.

Answer 1

The point-to-point integration of different microservices is hard to achieve because of the different technology stacks that may be used by a particular microservice that is present in the infrastructure. This may cause individual connectors to be built for every pair of microservices in order to translate the data format of one microservice to another.

Another bottleneck happens because of the scalability of these services, since now the connectors have to connect every single instance of the deployed microservice.

Answer 2

The enterprise service bus has been replaced with stateless message routers with the advent of microservice architecture, where these routers can be scaled up individually and implement message routing for the wide number of microservices that might be running inside an infrastructure.

Answer 3

The message brokers inside a microservice architecture provide high availability by replicating message queues between the multiple instances of the message broker that might be running. This allows the routers to take the place of a failing router and keep communication inside the infrastructure intact.
