Which programming language is mostly used by DevOps engineers?

In today’s fast-paced technological landscape, DevOps has become a cornerstone of software development, bridging the gap between development and operations teams to streamline workflows and improve efficiency. A critical component of this synergy is the use of programming languages that facilitate automation, integration, and management of systems. While there is no single language that dominates DevOps, several programming languages are highly popular within the DevOps ecosystem. In this blog, we will explore the most commonly used programming languages by DevOps engineers and why they are essential for modern DevOps practices.

1. Python: The King of DevOps Scripting

Python is arguably the most popular programming language used by DevOps engineers. Known for its simplicity, readability, and extensive support for various libraries, Python is a go-to language for writing scripts, automating repetitive tasks, and managing infrastructure.

Why Python is Essential for DevOps:

• Ease of Learning: Python’s simple syntax makes it easy to pick up, especially for beginners in both software development and DevOps.

• Automation and Scripting: DevOps often involves automating workflows, setting up CI/CD pipelines, or managing cloud infrastructure. Python’s extensive libraries, such as Boto3 (for AWS) and Paramiko (for SSH), allow engineers to automate these processes with minimal effort.

• Versatility: Python can be used across multiple platforms, making it ideal for both server-side scripting and tool integration.

• Community Support: With a vast global community, finding tutorials, documentation, and libraries for any DevOps-related task in Python is never an issue.

  
  

From automating cloud environments with AWS, Azure, or Google Cloud to managing Kubernetes clusters, Python has become the de facto language for DevOps engineers seeking efficiency and scalability.

2. Bash: The Classic Scripting Language

While Python is a highly versatile language, Bash scripting is indispensable for anyone working in a Linux or Unix environment. As a DevOps engineer, you will frequently interact with system-level processes, configuration files, and environments that rely heavily on command-line interfaces.

Why Bash is Important for DevOps:

• Native to Unix/Linux: Bash comes pre-installed in most Unix and Linux distributions, making it highly accessible for automating local scripts, performing system administration tasks, and managing configurations.

• Shell Scripting: Bash scripting is excellent for creating small automation scripts to manage deployments, configure environments, or automate file management tasks.

• Low-Level Control: Unlike high-level languages, Bash gives you direct access to operating system utilities and system calls, which is particularly useful for controlling processes and network configurations.

  
  

Although Bash might not be as versatile as Python, it is indispensable for managing systems and automating infrastructure tasks in Unix-based environments.

3. Go (Golang): The Cloud-Native DevOps Language

Go, also known as Golang, has gained massive popularity in the DevOps world, especially in cloud-native applications and microservices architecture. Developed by Google, Go is known for its high performance, efficient concurrency, and static typing.

Why Go is Gaining Traction in DevOps:

• Concurrency: Go’s lightweight goroutines allow it to handle multiple tasks simultaneously, making it ideal for network applications, monitoring tools, and microservices.

• Speed: Go is a compiled language, which gives it a performance edge over interpreted languages like Python and Bash. This makes it suitable for building high-performance systems and backend services.

• Cloud-Native: Go was the language of choice for creating Kubernetes, Docker, and many other cloud-native technologies. As a result, engineers who work in cloud environments or containerization ecosystems find Go invaluable for developing, managing, and maintaining applications.

  
  

If you're focusing on building or managing containerized applications, learning Go will open doors to more advanced DevOps projects.

4. Ruby: The Backbone of Infrastructure as Code

While Ruby may not be as prevalent as it once was, it remains a key language in DevOps due to its use in popular infrastructure automation tools like Chef and Puppet. These tools allow DevOps engineers to automate server configuration, application deployment, and resource management.

Why Ruby is Relevant in DevOps:

• Infrastructure as Code (IaC): Tools like Chef and Puppet, which are built on Ruby, allow you to define infrastructure configurations in code, making deployments repeatable and scalable.

• Readable Syntax: Ruby’s syntax is highly readable, making it easy to write and understand configuration scripts.

• Community and Ecosystem: Ruby has a well-established ecosystem, and its libraries, or "gems," offer various DevOps-related functionalities that can simplify many processes.

  
  

While Ruby might not be the first language you learn for DevOps, it is worth knowing if your infrastructure relies heavily on tools like Chef or Puppet.

5. JavaScript (Node.js): Expanding DevOps to the Frontend

Though traditionally seen as a frontend language, JavaScript, particularly in the form of Node.js, has expanded into DevOps due to the rise of full-stack development and the need for consistent environments across frontend and backend systems.

Why JavaScript is Used in DevOps:

• Full-Stack Integration: With Node.js, JavaScript can be used for backend scripting, allowing DevOps teams to use the same language for both frontend and backend development, thus simplifying integration and deployment processes.

• Automation: JavaScript-based tools like Grunt and Gulp are often used for automating frontend workflows, making JavaScript a useful tool in full-stack CI/CD pipelines.

• Serverless and Cloud Functions: JavaScript, through Node.js, is widely used in serverless architecture, such as AWS Lambda, Google Cloud Functions, and Azure Functions. As serverless computing grows in popularity, JavaScript's role in DevOps is expanding.

  
  

JavaScript might not be as central to DevOps as Python or Go, but its increasing use in serverless and cloud environments makes it a valuable skill for DevOps engineers focusing on full-stack development.

6. PowerShell: The Windows DevOps Language

For DevOps engineers working in Windows environments, PowerShell is an essential scripting language. Like Bash for Linux, PowerShell is a powerful tool for automating administrative tasks and managing system configurations on Windows servers.

Why PowerShell is Important for Windows DevOps:

• Windows Automation: PowerShell scripts are used to automate various administrative tasks like managing Active Directory, configuring IIS, and handling Windows Server environments.

• Cross-Platform Support: While PowerShell originated on Windows, it now supports cross-platform automation, making it useful for hybrid cloud environments where both Linux and Windows servers are used.

• Integration with Microsoft Tools: If your DevOps pipeline includes tools like Azure, SQL Server, or other Microsoft services, PowerShell’s deep integration with these platforms can make automation much smoother.

  
  

PowerShell is a must-learn for any DevOps engineer who manages Windows infrastructure or works heavily with Microsoft cloud solutions.

Conclusion

While Python is the most commonly used programming language for DevOps engineers, the right language for you depends on the specific tasks and environments you’re working in. Bash is essential for Unix-based automation, Go is perfect for cloud-native and containerized applications, and Ruby remains a key player in infrastructure automation with tools like Chef and Puppet. Additionally, JavaScript (Node.js) and PowerShell offer unique advantages in full-stack and Windows-based DevOps workflows, respectively.
