Go Language

Go-A programming language that makes it easy to build simple, reliable, and efficient software. It is also known as Golang. It is a compiled and statically typed language. It is not just a programming language but a language which include features such as garbage collection, limited structural typing, memory safety and CSP-style concurrent programming.

Miri Infotech is launching a product which will configure and publish Go Language, to produce free implementations of distributed or otherwise scalable and high availability which is embedded pre-configured tool with Ubuntu and ready-to-launch AMI on Amazon EC2 that contains Go Compiler and Text Editor. 

Before going into deep, one must have the knowledge and understand and learn the concept of concurrency associated with it.

Concurrency, by its design, enables you to efficiently use your CPU horsepower. Even if your processor just has 1 core, concurrency’s design enables you to use that one core efficiently. That is why you can typically have hundreds of thousands of concurrent goroutines (lightweight threads) running on a single machine. Channels and goroutines are central to distributed systems since they abstract the producer-consumer messaging paradigm.

Another thing a person must know is it’s another amazing feature of Interfaces. Interfaces enable loosely coupled or decoupled components for your systems. Meaning that a part of your code can just rely on an interface type and doesn’t really care about who implements the interface or how the interface is actually implemented.

Let us now have a brief look at what all other features are associated with Go.

These features are listed as below:

Features of Go Programming

  • Support for environment adopting patterns similar to dynamic languages. For example, type inference (x := 0 is valid declaration of a variable x of type int)
  • Compilation time is fast.
  • Go programs are simple, concise, and safe.
  • Production of statically linked native binaries without external dependencies.

Till here, we have studied about what actually a Go language is and what types of features it provides to its users for their ease and flexible to use.

But, one question arise that why one should learn this language or use it?

And to answer this question, we can say that:

We use this language to improve the working environment for its designers and their coworkers. It is more about software engineering than programming language research. Or to rephrase, it is about language design in the service of software engineering.”

In addition to, we have something more for Go and it can be looked at as follows:

  • Remote package management and online package documentation.
  • Distinctive approaches to particular problems
  • An interface system in place of virtual inheritance, and type embedding instead of non-virtual inheritance.
  • A toolchain that, by default, produces statically linked native binaries without external dependencies.

You can subscribe Go Language to an AWS Marketplace product and launch an instance from the Go Language product's AMI using the Amazon EC2 launch wizard.

To launch an instance from the AWS Marketplace using the launch wizard

1. Open the Amazon EC2 console at https://console.aws.amazon.com/ec2/.

2. From the Amazon EC2 dashboard, choose Launch Instance.

On the Choose an Amazon Machine Image (AMI) page, choose the AWS Marketplace category on the left. Find a suitable AMI by browsing the categories, or using the search functionality. Choose Select to choose your product.

3. A dialog displays an overview of the product you've selected. You can view the pricing information, as well as any other information that the vendor has provided. When you're ready, choose Continue.

4. On the Choose an Instance Type page, select the hardware configuration and size of the instance to launch. When you're done, choose Next: Configure Instance Details.

5. On the next pages of the wizard, you can configure your instance, add storage, and add tags. For more information about the different options you can configure, see Launching an Instance. Choose Next until you reach the Configure Security Group page.

6. The wizard creates a new security group according to the vendor's specifications for the product. The security group may include rules that allow all IP addresses ( access on SSH (port 22) on Linux or RDP (port 3389) on Windows. We recommend that you adjust these rules to allow only a specific address or range of addresses to access your instance over those ports.

7.When you are ready, choose Review and Launch.

8. On the Review Instance Launch page, check the details of the AMI from which you're about to launch the instance, as well as the other configuration details you set up in the wizard. When you're ready, choose Launch to select or create a key pair, and launch your instance.

9. Depending on the product you've subscribed to, the instance may take a few minutes or more to launch. You are first subscribed to the product before your instance can launch. If there are any problems with your credit card details, you will be asked to update your account details. When the launch confirmation page displays


Go is expressive, concise, clean, and efficient. It also provides a rich standard library. Go programming implementations use a traditional compile and link model to generate executable binaries. Code written in Go is easy to maintain. . Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction.


A Go program can vary in length from 3 lines to millions of lines and it should be written into one or more text files with the extension ".go".

  • A text editor
  • Go compiler

Text Editor

Text editor is used to type your programs. The name and version of text editors can vary on different operating systems. The files you create with the text editor are called source files. They contain program source code.

Go Compiler

The source code written in source file is the human readable source for your program. It needs to be compiled and turned into machine language so that your CPU can actually execute the program as per the instructions given. The Go programming language compiler compiles the source code into its final executable program.

There are basically two main goals one should follow and those are:

  • Spread data evenly around the cluster
  • Minimize the number of partition reads


  • The packages distributed with Go are pretty useful, but there are still some libraries you'll miss. Most notably a UI toolkit.
  • There is no support for generics in Go, although there are many discussions around it.
  • Go is not object oriented in the traditional sense.

Usage / Deployment Instruction

Step 1: Open Putty for SSH

Step 2: Open Putty and Type <instance public IP> at “Host Name” Type "ubuntu" as user      name Password auto taken from PPK file.

Step 3: Use following command to check Go version

>>$ go version

Step 4: Verify all configured environment variables using following command.

>>$ go env

Step 5: Now create your Go file with “.go” extension

>>$ vi hello.go

Step 5.1: Now enter the code you want to run.

Example: to print hello world.

Step 6: Now run your program.

>>$ go run hello.go
