What is DevOps?

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

This guide covers the tools, practices, and culture needed to implement DevOps successfully. From CI/CD pipelines and GitOps to testing automation and DevSecOps, learn how to accelerate software delivery while maintaining quality and security.

Frequently Asked Questions

Common questions about DevOps and CI/CD

What is the difference between CI and CD?
Continuous Integration (CI) automatically builds and tests code changes when merged. Continuous Delivery (CD) automatically deploys passing builds to staging environments. Continuous Deployment goes further, automatically deploying to production. CI ensures code quality; CD ensures rapid, reliable releases.
What is GitOps and how is it different from DevOps?
GitOps is a subset of DevOps that uses Git as the single source of truth for declarative infrastructure and applications. Changes are made via pull requests, and automated agents (like ArgoCD or Flux) sync the desired state to the actual state. GitOps provides better auditability, rollback, and security.
Should I use Jenkins, GitHub Actions, or GitLab CI?
Jenkins offers maximum flexibility and plugin ecosystem but requires more maintenance. GitHub Actions is best if you're already on GitHub with great integration and marketplace. GitLab CI provides an all-in-one DevOps platform with excellent security features. Choose based on your existing toolchain and operational capacity.
How do I implement DevSecOps?
Shift security left by integrating security scans into CI/CD: SAST (static analysis), DAST (dynamic testing), dependency scanning, container image scanning, and secrets detection. Use policy-as-code tools like OPA/Gatekeeper. Automate compliance checks and make security everyone's responsibility, not just the security team's.
