The course is part of this learning path
If you're thinking about engineering the next big dotcom application then you should seriously consider using Go!!
The Go Programming Language is without doubt one of the hottest languages to learn, particularly in this cloud native era. More and more companies are adopting Go to engineer highly performant, stable and maintainable applications. Popular projects such as Docker, Kubernetes, Terraform, Etcd, Istio, InfluxDB have all been built successfully using Go!!
This introductory level training course is designed to bring you quickly up to speed with the many key features that the Go programming language provides. You'll also learn how to setup your own Go development environment - consisting of the Go toolchain, Visual Studio Code, and several related Go based extensions - all to ensure that you are able to be productive writing your own source code.
We’d love to get your feedback on this course, so please give it a rating when you’re finished. If you have any queries or suggestions, please contact us at support@cloudacademy.com.
Learning Objectives
By completing this course, you will:
- Learn about what makes Go a great language
- Learn how to install the Go toolchain
- Learn how to setup Visual Studio Code to edit and debug Go programs
- Learn how to work with the Go Playground to test and run snippets of Go code
- Learn and understand the basic Go language syntax and features
- Learn how to use the Go tool chain commands to compile, test, and manage Go code
- And finally, you’ll learn how to work with and manage Go modules for module dependency management
Intended Audience
This course is intended for:
- Anyone interested in learning the Go Programming Language
- Software Developers interested in using Go to compile and test Go based applications
- DevOps practitioners looking to learn about Go to support Go based applications
Prerequisites
To get the most from this course, you should have at least:
- A basic understanding of software development and the software development life cycle
Source Code

- [Jeremy Cook] In this demo, I'll show you how to declare and work with variables of type Integer. On line eight, the count1 variable is declared as an Integer using the datatype int. In this case since we aren't explicitly initializing it, it will be set to it's zero value which for an Integer is zero. On line nine, the count2 variable is declared and initialized immediately to the Integer value 100. Lines 10 and 11 show you how to use the shortened syntax form where the compiler infers the integer datatype. Lines 21 and 22 show an example of using the plus plus and dash dash operators to increment and decrement the Integer variables.
Let's now run the program. And as expected, we get the following results.
In summary, I've shown you how to use the var keyword to declare a variable of type integer, how to initialize a variable of type integer, how an integer variable is initialized to its zero value which in this case is the value zero, how to declare and initialize an integer using the shorthand syntax, and how to use the plus plus and dash dash operators to increment and decrement the Integer variables.
Note that there are many more other more refined numeric-based data types in Go such as Floats declared using float32 and float64 data types, and Complex Numbers declared using complex64 and complex128 data types.
