What is a DevOps Engineer?

A DevOps Engineer is a professional who bridges the gap between software development (Dev) and IT operations (Ops). They focus on automating, optimizing, and managing the processes involved in building, testing, deploying, and monitoring software applications. The role emerged from the DevOps philosophy, which emphasizes collaboration, continuous improvement, and efficiency in delivering high-quality software.

In practice, a DevOps Engineer typically:

* Designs and implements automated workflows (CI/CD pipelines) using tools like Jenkins, GitLab CI, or GitHub Actions.

* Manages infrastructure through code (Infrastructure as Code) with tools like Terraform or Ansible.

* Works with cloud platforms such as AWS, Azure, or Google Cloud to deploy and scale applications.

* Monitors system performance and ensures reliability using tools like Prometheus, Grafana, or Datadog.

* Collaborates with developers and operations teams to streamline releases and troubleshoot issues.

The role requires a mix of coding skills, system administration knowledge, and familiarity with tools for automation and containerization (e.g., Docker, Kubernetes). Essentially, a DevOps Engineer helps teams deliver software faster, more reliably, and at scale.
