Hands-On Software Architecture with Golang

By: Jyotiswarup Raiturkar

Overview of this book

Building software requires careful planning and architectural considerations; Golang was developed with a fresh perspective on building next-generation applications on the cloud with distributed and concurrent computing concerns. Hands-On Software Architecture with Golang starts with a brief introduction to architectural elements, Go, and a case study to demonstrate architectural principles. You'll then move on to look at code-level aspects such as modularity, class design, and constructs specific to Golang and implementation of design patterns. As you make your way through the chapters, you'll explore the core objectives of architecture such as effectively managing complexity, scalability, and reliability of software systems. You'll also work through creating distributed systems and their communication before moving on to modeling and scaling of data. In the concluding chapters, you'll learn to deploy architectures and plan the migration of applications from other languages. By the end of this book, you will have gained insight into various design and architectural patterns, which will enable you to create robust, scalable architecture using Golang.

Scalability bottlenecks

Scalability bottlenecks are those system aspects that serialize (or choke) parallel operations. With bottlenecks, the ability of the system to do more work in parallel drops; hence, a major design objective of scalable systems is to remove these bottlenecks.

To understand system bottlenecks, let's look at a couple of very interesting problems that were encountered by architects in the recent past:

  • The C10K problem: A web server bottleneck observed with the Apache server.
  • The Thundering Herd problem.

The C10K problem

At the start of the 21st century, engineers ran into a scalability bottleneck: web servers were not able to handle more than 10,000 concurrent connections. For example, for the Apache...
