There are some misconceptions around who DevOps Engineers are and what do they do – do they write codes or are they responsible for system engineering?

We will help you clear any doubts that you might have and help you understand who exactly is a DevOps Engineer.

But before we move onto the roles and responsibilities, let us first understand what DevOps is.

What is DevOps?

DevOps, as its name (Dev + Ops) suggests, is a compilation of Development and Operations.
It is a phenomenon used for bringing balance to the software development lifecycle by bridging the gap between the company’s developers and the IT team. With DevOps, organizations can release small features or regular updates and receive feedbacks faster as it reduces software failures and shortens the lead time between bug fixes.

DevOps handles multiple technologies to develop CI/CD automation pipelines – development, testing, and deployment. Now, to streamline these processes, a DevOps engineer is required.

Who is a DevOps Engineer?

A DevOps engineer is a person who fully comprehends the software development cycle, with the knowledge and understanding of tools, processes, and other methodologies. While the developers work on new features of the apps and the IT operators work towards stabilizing the app after the release, a DevOps engineer unifies and automates these processes. A DevOps engineer is required to work with the company’s software development team, the system operators & admins, as well as the IT operations team to administer code releases, the app’s or product’s maintenance and management, deployments, etc. on a CI/CD (continuous delivery/continuous deployment) basis.

Some of the commonly used tools a DevOps engineer uses include:

  • Source code management tools (Version Control System) – Git & GitHub
  • Automation server, alongside plug-ins built for CI/ CD pipelines development tool – Jenkins
  • Automation tester tool – Selenium
  • Software/App Containerization Platform – Docker
  • Container Orchestration Platform – Kubernetes
  • Configuration Management & Deployment tool – Puppet
  • Another Configuration Management & Deployment tool – Chef
  • Configuration Management & Deployment – Ansible
  • Continual Monitoring tool – Nagios

A DevOps engineer is needed at various levels of a software development cycle. So, if you are thinking of making a shift to this career, learn DevOps and get a DevOps certification because it is a great path.

Now the question is, how can you become a DevOps engineer? What exactly will be your role in an organization?

Let’s understand what are the tasks that a DevOps engineer performs regularly.
