What is DevOps Engineering?

Software development (Dev) and IT operations (Ops) are fundamentally combined in DevOps. DevOps engineers focus on automating and streamlining the development lifecycle, ensuring faster delivery of software with higher reliability. By fostering collaboration between development and operations teams, DevOps eliminates traditional silos, enabling smoother workflows and a culture of continuous improvement.

Roles of a DevOps Engineer

A DevOps engineer is the glue that holds the development and operations teams together. Here are some of their key roles:

• Collaborator: Bridges communication gaps between developers, testers, and IT operations to achieve shared goals.
• Automation Specialist: Implements automation tools and processes to enhance efficiency and minimize manual tasks.
• Infrastructure Manager: Designs, builds, and maintains scalable and secure IT infrastructure.
• Monitoring Expert: Sets up tools to monitor application performance, ensuring systems remain reliable and resilient.
• Security Advocate: Integrates security measures (DevSecOps) throughout the software development lifecycle.
