DevOps Guide

What is DevOps?

DevOps is a set of practices that combines software development (Dev) and IT operations (Ops). It aims to shorten the systems development life cycle and provide continuous delivery with high software quality.

Core DevOps Practices

Continuous Integration (CI)

Automatically integrate code changes into a shared repository multiple times a day, verifying each integration with automated builds and tests.

Continuous Delivery (CD)

Automatically prepare code changes for release to production and deploy with a single click when ready.

Infrastructure as Code

Manage and provision infrastructure through code instead of manual processes.

Monitoring and Logging

Monitor applications and infrastructure to ensure availability and performance.

Essential DevOps Tools

Version Control

Git, GitHub, GitLab, Bitbucket

CI/CD Tools

Jenkins, GitLab CI, GitHub Actions, CircleCI

Configuration Management

Ansible, Puppet, Chef, Terraform

Containerization

Docker, Kubernetes, OpenShift
