Learn a Programming Language

Learn a Programming Language

To kick-start your learning journey for any operations role, first you need to learn and practice different programming languages. Make sure to get well-versed with a few programming languages. Though you may not need to write code as DevOps Engineer, you may need to review and debug it. 
 

  • Python
  • Python

    Python is a general-purpose programming language designed by Guido Van Rossum in 1991. Task automation, data analysis, and data visualization are some primary applications of Python that make it an ideal language to use in DevOps. 
     

  • C++
  • C++

    C++ is an object-oriented programming language designed as an extension to the C language by Bjarne Stroustrup in 1985. For writing highly-optimized and high-performance code, C++ is an ideal programming language. 
     

  • Java
  • Java

    Java is a high-level, class-based programming language developed by James Goslings in 1995. The Write Once, Run Anywhere (WORA) feature of Java makes it more popular among developers. Many platforms and companies leverage Java for creating solutions, and having Java in your skillset is beneficial. 
     

  • Ruby
  • Ruby

    Ruby is a high-level, general-purpose programming language developed by Yukihiro Matsumoto in 1995. It is an ideal language for web development, along with infrastructure management. The flexibility Ruby offers while writing code makes it a great choice to use for DevOps infrastructure. 
     

  • JavaScript
  • JavaScript

    JavaScript is a scripting language and one of the core technologies of the World Wide Web (WWW) developed by Brendan Eich in 1995. As it enables the development of the client-side as well as server-side, it has a lot of use in the DevOps environment. 
     

  • Go
  • Go

    Go or Golang is quite a new language as compared to others developed by Robert Griesemer, Rob Pike, and Ken Thompson in 2009. It offers excellent flexibility that the DevOps environments need, and hence, is very useful in DevOps. 
     

Work with different OS

Work with different OS

Operating systems is another significant technology stack that any professional in DevOps needs to work with. They play a vital role in running the servers that host deployed applications. Linux, Unix, and Windows are three popular operating systems you must consider learning. 
 

  • Linux
  • Linux

    Linux is a group of Unix-like, open-source operating systems developed in 1991. It is based on the Linux kernel, which is an operating system kernel developed by Linus Torvalds in 1991. This operating system is for computers, servers, mobile devices, mainframes, and embedded devices. 
     

  • Unix
  • Unix

    Unix is a family of multi-tasking and multi-user computer operating systems developed in 1969 by some professionals at AT&T lab. It was one of the first operating systems written in the C language. In addition, it is widely used in PCs, servers, and mobile devices.  
     

  • Windows
  • Windows

    Windows is one of the most popular and widespread operating systems developed by Microsoft. It is a graphical user interface (GUI), having the two most common editions, Windows Home and Windows Professional. It is used in a wide range of devices, including PCs, mobile devices, tablets, servers, and game consoles.
     

Understand the OS concepts

Understand the OS concepts

As a developer, it is essential to possess a profound knowledge of the basic concepts of OS. You may encounter a lot of issues while developing applications that may be due to operating systems. So, it is important to understand the core concepts and working of OS. 
 

  • Process Management
  • Process Management

    A process is simply any program written in a text file and is currently in execution. It is generally divided into four parts, namely stack, heap, text, and data. Process management is a systematic approach to creating, scheduling, and terminating processes and avoiding a deadlock. 
     

  • Terminal Commands
  • Terminal Commands

    A terminal, often called a console or command line, allows users to automate and accomplish different tasks on computer systems without a graphical user interface (GUI). It lets users send simple text commands to their computer systems and perform various tasks, like copying a file or navigating through a particular directory. 
     

  • Virtualization
