Introduction
In a world driven by continuous innovation and fast-paced software delivery, DevOps has become the glue between development and operations. It ensures that code reaches production faster, safer, and more efficiently. Whether you’re a developer, system admin, or fresh tech graduate, entering DevOps in 2025 opens the door to high-impact roles, lucrative salaries, and the power to automate the future.
Who is a DevOps Engineer?
A DevOps Engineer bridges the gap between developers and IT operations. They implement automation across the software lifecycle—from code integration to production deployment. A successful DevOps engineer wears many hats: coder, infrastructure manager, security enforcer, and deployment strategist.
