DevOps Prerequisites

Before discussing the Prerequisites for learning DevOps, let's first provide an overview of what DevOps is.

WHAT IS DEVOPS?

DevOps is a set of practices that combines software development (Dev) and information technology operations (Ops) to shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives. It is the union of people, processes, and technology to continually provide value to customers.

The name "DevOps" is a combination of "development" and "operations," which reflects the focus on improving collaboration and communication between these two teams in order to deliver software faster and with higher quality. With the rise of digital business, companies are under pressure to deliver software updates and new features more quickly and more frequently; this is where devOps comes in.

The main objective of DevOps is to improve collaboration and communication between development and operations teams in order to deliver software faster and with higher quality. This is achieved by automating the software delivery process and making it more efficient through the use of tools such as continuous integration, continuous delivery, and infrastructure as code.

DevOps also emphasizes the use of agile and lean methodologies which prioritize the rapid delivery of small, incremental changes to software rather than large, infrequent updates. This approach allows for faster feedback and the ability to quickly respond to changes in customer demand or market conditions.

The culture of DevOps is one of collaboration, experimentation, and continuous learning. It promotes a shared responsibility for the entire software delivery process, from development and testing to deployment and maintenance. This helps to break down silos between teams and encourages a culture of shared ownership and accountability.

Overall, DevOps is a culture, movement, and practice that emphasizes communication, collaboration, and integration between software developers and IT professionals. It aims to deliver software faster and with higher quality by automating the software delivery process and making it more efficient.

Are you a devOps enthusiast and want to know the basic knowledge required to kick-start a devOps career?

This piece will provide an overview of the foundational requirements for learning DevOps. It is important to have a solid foundation before diving into DevOps, and this article will highlight the necessary prerequisites to begin your learning journey. Having an understanding of these prerequisites will make the process of learning DevOps smoother and easier: 👇

The Prerequisites:

• Overall Computer Science knowledge (basic)

• Passion for devOps

• Basic understanding of Linux/Unix system concepts and administration

• Linux networking basics

• Familiarity with at least one cloud provider (Azure, AWS, GCP)

• Familiarity with command-line interface (CLI)

• Knowing how to build and deploy process works

• Familiarity with text editor

• Basics of Vagrant

• Good to know basic scripting language like python, bash scripting

• Basics of applications – Java, NodeJS, Python

• Web servers – Apache HTTPD, Nginx, G-Unicorn, PM2

• Knowledge of Databases – MySQL, MongoDB

I would recommend this prerequisite course: https://youtu.be/Wvf0mBNGjXY by Mumshad Mannambeth to start your journey. After acquiring a solid understanding of the foundational concepts, you can then proceed to delve deeper into learning DevOps and its associated tools. This can be done by starting at a beginner level and gradually working your way up to more advanced topics. By following this progression, you will be able to ascend the "stairs" of DevOps with ease.

Resources to learn devOps are everywhere, there are great learning platforms for devOps; both paid and free ones such as YouTube to get started. It is important to follow a roadmap and as well identify the right resources to use.

Practical experience can also enhance your understanding, so creating an account on AWS, Azure, or GCP (either with a free or paid subscription) will provide an opportunity to explore and practice as you learn. This hands-on approach will make the concepts stick better than just reading theories.

Lastly setup your own lab in your environment for practising 💻. It is normal to fail in your lab, don't be afraid of failing, as we all have at some point!

🎯 Happy learning 🤗

💻 Learn and loud better!
