Yes! It is used. Golang for enterprise for software development has not been completely adopted by the people they originally intended, namely, the people who use C and C++, it nevertheless found its use in a multitude of places and people who use Python, Ruby, Javascript frameworks are switching to Go for developing applications.  

Go language is designed by a team of some of the veterans in programming that consists of people who worked on UNIX and also people having decades of experience with compiler design. They created this new language to address the issues they have faced in their entire career. Even though they generally started from C, Go has designed from scratch keeping the best of languages of C/C++ and getting rid of bad features.

Enterprise applications are complex applications that satisfy critical business requirements. They often are multi-developer and multi-component applications. Also, these days enterprise applications are also deployed on cloud and their functionality is demanded by multiple concurrent users.

So, enterprise applications should be highly performing — to solve problems in a reasonable amount of time and must be readable so as to maintain it. You could see that all of these features are part of the core design principles of Go!

The primary reason that drives Golang for enterprise software development is its support to highly scalable software development along with an emphasis on readability and robustness.

How does Go ensure its promises?

• Go ensures readability by having only a small number of constructs and ways of combining them. Also, it omits a sizable amount of features from modern programming languages just to ensure readability. It also has given a standard for the code format and tools for automatic formatting of your code for adhering to it!
• Go ensures performance by making it a compiled language rather than interpreted one. Though interpreted language could have some quirks, they are slow to execute because every line must be translated separately into machine code and then executed. With the compiler, all of the code would be converted into machine code at once and then executed. Also, Go’s compilers are highly optimized which all together give highly performing applications.
• One of the main ways Go ensures scalability by providing high support for concurrency. With its goroutines, channels, and other constructs, Go programmers can easily and efficiently implement concurrency in their applications without too much resource usage. However, developers need to be aware of the general risks of the concurrency including deadlocks.

Also, Golang web development is a breeze, as its library provides many tools that cater to different needs. Many poise that Go could replace Node.js. Go lang powers many successful applications like Docker and Kubernetes. The notable companies using golang are Google, Uber, Dropbox, Soundcloud, and more.

Of course, I have only provided the main features of Go that make it compelling to use for the development of enterprise applications. There are lots of other features of Go that make it good and also, with the coming of Go 2.0, we can certainly expect more!
