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.

Scaling Applications

Scalability is the attribute of a software system that allows it to handle an increased amount of work with proportionally more resources, while still maintaining the service level agreements (SLAs) that the system offered. A scalable system allows you to solve an increased amount of traffic/work by throwing money at the problem; that is, by adding more hardware. A non-scalable system simply cannot handle the load, even with increased resources.

For example, consider a backend software service that provides an API that is useful for an app. But it is also important that the API returns data within a guaranteed amount of time so that users don't experience latency or unresponsiveness at the app. A system not designed with scalability in mind will behave as shown here:

With an increase in traffic, the response times go through the roof! In contrast, with...
