What is DevOps?

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops) to shorten the systems development life cycle while delivering features, fixes, and updates frequently in close alignment with business objectives.

Why DevOps Matters

DevOps addresses the traditional conflict between development teams (who want to deploy new features quickly) and operations teams (who want to maintain system stability):

DevOps Principles

Continuous Integration

Developers merge code changes frequently (at least daily) into a shared repository where automated builds and tests verify the changes.

Continuous Delivery

Code changes are automatically built, tested, and prepared for release to production, enabling rapid and reliable software delivery.

Infrastructure as Code

Managing and provisioning infrastructure through code and automation rather than manual processes.

Monitoring & Logging

Tracking application and system performance to understand impact on user experience and inform improvements.

Communication & Collaboration

Breaking down silos between development, operations, and other stakeholders through shared tools and processes.

Security Integration

Building security into the development process from the beginning rather than adding it at the end (DevSecOps).
