Go: Building Web Applications

By: Nathan Kozyra, Mat Ryer

Overview of this book

Go is an open source programming language that makes it easy to build simple, reliable, and efficient software. It is a statically typed language with syntax loosely derived from that of C, adding garbage collection, type safety, some dynamic-typing capabilities, additional built-in types such as variable-length arrays and key-value maps, and a large standard library. This course starts with a walkthrough of the topics most critical to anyone building a new web application. Whether it’s keeping your application secure, connecting to your database, enabling token-based authentication, or utilizing logic-less templates, this course has you covered. Scale, performance, and high availability lie at the heart of the projects, and the lessons learned throughout this course will arm you with everything you need to build world-class solutions. It will also take you through the history of concurrency, how Go utilizes it, how Go differs from other languages, and the features and structures of Go's concurrency core. It will make you feel comfortable designing a safe, data-consistent, and high-performance concurrent application in Go. This course is an invaluable resource to help you understand Go's powerful features to build simple, reliable, secure, and efficient web applications.

Chapter 3. Developing a Concurrent Strategy

In the previous chapter, we looked at the concurrency model that Go relies on to make your life as a developer easier. We also saw a visual representation of parallelism and concurrency. These help us to understand the differences and overlaps between serialized, concurrent, and parallel applications.

However, the most critical part of any concurrent application is not the concurrency itself but communication and coordination between the concurrent processes.

In this chapter, we'll look at creating a plan for an application that heavily factors communication between processes and how a lack of coordination can lead to significant issues with consistency. We'll look at ways we can visualize our concurrent strategy on paper so that we're better equipped to anticipate potential problems.

Applying efficiency in complex concurrency

When designing applications, we often eschew complex patterns for simplicity, with the assumption...
