Go fundamentals

Develop backends and web services in Go

3 days / 21h

Course overview

Golang is becoming the preferred language for the cloud. First released by Google in 2012, it’s easy to install and there are a wealth of available libraries in a variety of domains. Statically typed, succinct, coming with a performant garbage collector, it’s built from the ground for powerful and easy concurrent programmation. Fast compiling, with low memory imprint, it optimizes machine resources.

These features are the reason why Go is the language of choice for the implementation of modern, simple and light microservices.

At the end of this training you will master the fundamental aspects of Go programming. You will be able to use the Go ecosystem to your advantage and quickly create powerful and maintainable additions to your information system.
You’ll enjoy coding on the backend side again and will leave us confident in the achievement of your objectives.
