As we already know that DevOps is one of the trendiest technology. If you want to give an extra boost to your career then you have to join DevOps Online Training.
There is a lot of confusion regarding – Who is a DevOps Engineer? He writes code and oversees the work of a System Engineer, isn’t he? Good! Not quite. Here I will explain what a DevOps Engineer does and the responsibilities he has.

Before that, we should understand DevOps.
What is DevOps?
Developers and IT staff can work together on developing software using DevOps.
The benefits of DevOps include the ability to release small features very quickly and to incorporate feedback from the users immediately.
- Fewer Software Failure
- Shortened lead time between fixes
A waterfall model has many limitations and this model overcomes all of them. For developing CI/CD pipelines, DevOps processes involve a range of developments, tests, and deployments.
Following are some of the famous DevOps tools:
- Git and GitHub – Source code management (Version Control System)
- Jenkins – Automation server, with plugins built for developing CI/ CD pipelines
- Selenium – Automation testing
- Docker – Software Containerization Platform
- Kubernetes – Container Orchestration tool
- Puppet – Configuration Management and Deployment
- Chef – Configuration Management and Deployment
- Ansible – Configuration Management and Deployment
- Nagios – Continuous Monitoring

Who is a DevOps Engineer?
DevOps Engineers understand the Software Development Lifecycle and can effectively build pipelines for the development of digital products (CI/CD pipelines).
Developers and IT staff coordinate the process of releasing new code as a DevOps Engineer. Developers or sysadmins who are passionate about scripting and coding and move into the development side to provide better simulation planning and deployment are two examples.
DevOps Job Roles and Responsibilities:
The role of a DevOps engineer varies from organization to organization, but invariably entails some combination of release engineering, infrastructure provisioning and management, system administration, security, and DevOps advocacy.
The build and deployment of application code are both parts of release engineering. In reality, specific tools and processes can vary significantly based on several variables including who is writing the code, the degree to which pipelines are automated, and whether the platform is on-premises or in the cloud.
It might be necessary to select, provision, and maintain CI/CD tools or to write and maintain bespoke build/deploy scripts as part of release engineering.
Infrastructure provisioning and system administration include deploying and maintaining the servers, storage, and networking resources required to host applications.
This might include managing servers, storage devices, switches, and virtualization software in a data center for organizations with on-premise resources. Typically, when a hybrid or fully cloud-based organization uses those components, virtual instances of those components must be provisioned and managed.
DevOps advocacy is often underestimated or overlooked but is arguably the most important role for a DevOps engineer. Engineering teams may find the transition to a DevOps culture a bit confusing and disruptive.
The DevOps engineer’s role is to evangelize and educate the DevOps way throughout the organization as the subject matter expert for DevOps.
Other roles and responsibilities
In this role, the DevOps expert promotes and develops DevOps within the company. It is typically the DevOps evangelist’s role to speak to people and improve processes in an interpersonal manner.
Release manager/change advisory board
Those organizations that are still in the process of transitioning to DevOps may have a separate group called a change advisory board (CAB) or an individual release manager role.
As such, they ensure the quality and security of new application software released into production, as well as the approval of management.
In the case of riskier software releases, these roles were especially important. The importance of these roles is diminishing (or even disappearing) with technologies like automated tests and dark deployments.
Every DevOps engineer is expected to have expertise in automation. Yet it is not unheard of for an organization to have a separate automation expert or automation engineer role. This may be someone whose focus is to manage the CI/CD tooling or develop and maintain automated test suites.
Developers who write both front-end and back-end code are often referred to as software developers. These are the people who have been historically described as “computer programmers” before the rise of agile thinking. Are you excited to learn DevOps right now?
