What is Go?
Go, or Golang is an open-source programming language developed at Google. The designers of Go wanted developers to have a programming language that made it quick and easy to develop applications. Go is used on servers, web development, and even command-line interfaces, and it is built to be simple, high-performing, readable, and efficient.
Actually, It is Go or Golang?
You might hear the language called both Go and Golang, which might be confusing. I once thought they were names for different languages. But Golang is just another name for Go — and Go remains the official name.
The language is called Go. The “golang” moniker arose because the web site is golang.org, not go.org, which was not available to us. Many use the golang name, though, and it is handy as a label. For instance, the Twitter tag for the language is “#golang”. The language’s name is just plain Go, regardless.
A side note: Although the official logo has two capital letters, the language name is written Go, not GO.
Usage
Is Google using Go internally?
Yes. Go is used widely in production inside Google. One easy example is the server behind golang.org. It’s just the godoc document server running in a production configuration on Google App Engine.
A more significant instance is Google’s download server, dl.google.com, which delivers Chrome binaries and other large installables such as apt-get packages.
Go is not the only language used at Google, far from it, but it is a key language for a number of areas including site reliability engineering (SRE) and large-scale data processing.
What other companies use Go?
Go usage is growing worldwide, especially but by no means exclusively in the cloud computing space. A couple of major cloud infrastructure projects written in Go are Docker and Kubernetes, but there are many more.
It’s not just cloud, though. The Go Wiki includes a page, updated regularly, that lists some of the many companies using Go.
The Wiki also has a page with links to success stories about companies and projects that are using the language.
The following sections group companies using Golang by domain. Each company section includes details found online, often in articles. I hope those materials that will help you get a better picture of Golang use cases across companies.

Why are companies using Golang?
Designed for multi-core processing
Golang was created with cloud computing in mind. It leverages concurrency and parallelism provided by modern hardware.
It’s approach to concurrency is very easy to work with. Compared to Python/Java, running a function on a goroutine requires minimal boilerplate code.
The goroutines and channel-based approach to concurrency makes it very easy to use all available CPU cores and handle concurrent IO without complicating development.
Created for large projects
Over time new complex systems were built on top of these foundational systems/libraries and languages. People too often don’t think of the hidden costs of complexity. The truth is that code is read many more times than it is written. Team velocity is significantly burdened by complexity.
Go code is very straightforward and readable. This simplicity empowers teams to collaborate in ways never before possible.
Easy to learn
The minimal layout and specifications of the Golang language make it very easy to read, even if you are new to programming languages.
Go is simple to learn, especially if you have a background in C or Java. Even as a beginner, it’s easier to get the hang of the language in comparison to older competitors.
If you are already familiar with other programming languages, then it typically takes around a week to get the hang of Go. Beginners will be looking at a few weeks up to several months, depending on their dedication
What IDEs does Go support?
The Go project does not include a custom IDE, but the language and libraries have been designed to make it easy to analyze source code. As a consequence, most well-known editors and IDEs support Go well, either directly or through a plugin.
The list of well-known IDEs and editors that have good Go support available includes Emacs, Vim, VSCode, Atom, Eclipse, Sublime, IntelliJ (through a custom variant called Goland), and many more. Chances are your favorite environment is a productive one for programming in Go.
Why You Should Learn to Go
Easy Learning Curve
Go is one of the simplest programming languages out there. It is easy to pick up, especially if you already have knowledge of any other programming language. In my case, I learned the fundamentals of Go in one sitting.
A lot of developers who use Go and are confident in their teaching abilities say that they can get an absolute beginner to build an app with Go in just a few hours.
Active Community and Good Documentation
Go has solid and easy-to-read documentation. You can read the documentation on the official website.
Apart from documentation, Go also has a supportive and active community behind it, so you can always get help when you are stuck.
The hashtag #golang is commonly used on Twitter, so in case you get stuck, you can tweet your question and attach the hashtag to it.
You Can Get a lot Done with Go
Go is a multipurpose programming language, meaning you can use it for a number of things, such as web development, data science, cloud computing, and more.
If you want to have a career in cloud-based programming, you should consider learning Go, because platforms such as Amazon Web Services, Kubernetes, and Google Cloud Platform (GCP) all support it.
Attractive Wages
According to the 2020 StackOverflow Developer Survey, Go developers are the third-highest paid after Perl and Scala, with a median salary of $74K.
This figure will probably continue to climb because Go continues to gain popularity every year and is in demand. So, if you want to earn more money, you should consider learning to Go.
