Software Architecture with Python

By: Anand Balachandran Pillai

Overview of this book

This book starts by explaining how Python fits into an application's architecture. As you move along, you will get to grips with architecturally significant demands and how to determine them. Later, you’ll gain a complete understanding of the different architectural quality requirements for building a product that satisfies business needs, such as maintainability/reusability, testability, scalability, performance, usability, and security. You will also use various techniques such as incorporating DevOps, continuous integration, and more to make your application robust. You will discover when and when not to use object orientation in your applications, and design scalable applications. The focus is on building the business logic based on the business process documentation, and understanding which frameworks to use and when to use them. The book also covers some important patterns that should be taken into account while solving design problems, as well as those in relatively new domains such as the Cloud. By the end of this book, you will have understood the ins and outs of Python so that you can make critical design decisions that not just live up to but also surpassyour clients’ expectations.

Chapter 4. Good Performance is Rewarding!

Performance is one of the cornerstones of modern-day software applications. Every day we interact with high performing computing systems in many different ways, as part of our work and our leisure.

When you book an airline ticket from one of the travel sites on the web, you are interacting with a high performance system that carries out hundreds s of such transactions at a given time. When you transfer money to someone or pay your credit card bill online via an Internet banking transaction, you are interacting with a high performance and high throughput transactional system. Similarly when you play online games on your mobile phone and interact with other players, again there is a network of servers built for high concurrency and low latency that is receiving input from you and thousands of other players, performing computations at the back and sending data to you – all with reasonable and quiet efficiency.

Modern day web applications that serve millions...
