Top 10 Scripting Languages in DevOps – 2021


Software engineers and IT professionals often get confused when it comes to learn which programming or scripting language is good for their career as a DevOps engineer? This has led several of our readers to ask “What are the best Programming or Scripting languages for a DevOps engineer” and “Is Programming or Scripting knowledge is mandatory to learn for DevOps Engineers?” So, let’s dig answers of all these questions.

After reading this article you will be able to;

  • What are scripting languages?
  • What is the difference between Compiler and Interpreter?
  • Wht is the difference between Programming language and scripting language?
  • Is Programming or Scripting knowledge required or not to learn DevOps?
  • What are the top 10 scripting languages for DevOps engineers?
    • Python
    • Bash
    • Go language
    • Ruby
    • Groovy
    • Perl
    • Microsoft PowerShell
    • JAVAScript
    • Terraform
    • Ansible

Machine language is the lowest language level of the programming language and is the only one which computers can understand. For us (humans) it is not possible to write a program in Machine language which we often say Binary Code 0,1. This is the reason we use high-level programming languages which in the end converted into Machine language to run on a computer or system.

But, the thing here is to understand “what is scripting language?” we must understand the difference between programming and scripting language.

They both are high-level languages and use to instruct a machine. Now the question here is, if both are used for the same purpose then why do we have two different names.

As far as the language structure concern they both are the same, in fact, we can say all scripting languages are programming languages.

The major difference is scripting language does not require pre-compilation rather they are interpreted

So let’s try to understand what exactly is compilation and interpretation means?

Compiler takes the complete source file at once and converts it to the machine code with final executable which will be platform-dependent and can be run on the desired platform to produce desirable outputs. The interpreter also does the same thing to compile the high-level language to machine language, but it does it line by line at run time. Which means whenever it encounters the statement it converts the corresponding machine code which will be executed to produce output.

We may understand the difference with below-mentioned points:-


  • Source code privacy
  • Fast
  • Platform dependent
  • Require extra compilation step
  • It read and analyze the code only once


  • Can work on cross-platform
  • No source code privacy
  • Slow
  • No extra compilation delay
  • It read and analyze the code statements each time

So, now let’s unedrstand what is the difference between Programming and Scripting Languages?

Programming language:-

  • It used to create a standalone application which we can install anywhere based on the platform for which we have program it
  • It uses compiler to covert high-level languages into machine language
  • Examples:- C, C++, Java
  • In programming languages whatever softwares we make, we use one particular language to create that application or software. Which means let’s suppose we have made complete software with “C” language than it means that software is completely based on “C” language only.

Scripting language:-

  • It used to create a web application or similar like softwares.
  • It uses interpreter to convert high-level language into machine language
  • Examples:- JAVA Script, PHP, Python, BASH
  • Here let’s suppose we have made a software in PHP then it’s possible to use HTML or JAVA which means we can use scripting languages with multiple programming languages

Is Programming or Scripting knowledge is required to learn DevOps?

In DevOps, we use so many tools to automate our tasks. Most of the DevOps tools are GUI-based and some of the tools may be using scripting or commands to make it work. But programmers are going to write the codes and they will push it into the GIT or any similar tools. As a DevOps engineer, you need to create the CI/CD pipeline by using all the available tools in your infrastructure or in your work environment.

So, as a DevOps engineer, you don’t need to write any code. You will use multiple tools to make sure that codes are built appropriately and deployed in the target environment. Therefore, we can say, without programming knowledge you can fulfill your DevOps engineer role without any issues.

But, if you will have some understanding or knowledge of modifying the existing scripts or if you can write small-small programs then it is going to be really helpful in the long run. You don’t need to be a Coding master to switch your career in DevOps, even if you are a non-programmer, you can go for it.

Having said that, to be a pro in DevOps one can learn different programming and scripting languages that are commonly used in DevOps methodology to drive automation.  

Here we are going to list out the top 10 scripting languages for a DevOps engineer.
