It is essential to understand that DevOps is not just for engineers but system engineers. It's for everyone passionate about changing practices and new technologies and willing to work in a collaborative environment where everything is automated to make life simple.
It doesn't matter if you are a developer, sysadmin, tester or support engineer, performance engineer, or support engineer. Consider the DevOps Training for mastering the skill. You can become a DevOps engineer as you're already within an IT system responsible for deploying and managing production applications.
This article provides a guideline on how to be prepared for tools and technology to be a DevOps engineer who follows the DevOps principle.
NOTE: In this article, I've covered several areas. Anyone new cannot be an expert in every aspect. But, having a decent amount of experience in these areas can make you a DevOps engineer.
Learn about DevOps Culture
To become a DevOps engineer, the most crucial step is to comprehend what is the DevOps style of working. It's all about diverse teams working toward an end purpose. That is why there should not be any blame game between the different departments of IT.
For example, if you're a developer, Never say, "It's your job" You can say, "Let me see what I can do to assist." What you do can have a significant influence on the collaboration. (It does not mean you need to feed people with spoons and perform other people's work.)
NOTE: If you are newer, understanding the cultural aspects can be difficult because it is based on working experience in the industry. My advice is to concentrate on the fundamental IT fundamentals (OS Networking, OS, and programming)
IT executives and decision-makers must ensure that all team members are trained on DevOps culture aspects before implementing DevOps tools. This will help avoid confusion within the teams. This isn't the norm in companies that do, but they can often create a " DevOps Team" for operations and become a siloed organization.
People will likely stop hiding their truths and cease blaming other people for issues with projects when they realize that a problem in the project's delivery must be dealt with in a cooperative way rather than blame. As an example, an unrepentant postmortem.
Once you know the DevOps philosophy, you'll cease to say that " CI/CD and infrastructure automation is DevOps."
I suggest you read the current state of the DevOps report written by puppet. It is a must-read report for devops leaders and engineers.
