Understanding Golang and Goroutines

Let’s start with the basics

This article is focussed on understanding the basics of Golang. We will talk about the performance aspect of Golang and we will try to scale up the application by creating simple Goroutines.

We will also focus on underlying execution logic and what makes Golang different from other languages.

Concurrency in Golang

Before we proceed with the article, we need to understand the concept of parallelism and concurrency. Golang is capable of bringing both concurrency and parallelism to the application.

Let's understand the basic difference.

Understanding Concurrency

Concurrency means that the application has more than one thing to do at the same time. It's about creating multiple processes executing independently.

Applications might be dealing with lots of processes together to accomplish the intended behavior. Let's assume a simple ecommerce website and evaluate the list of concurrent tasks that it needs to execute:
