Devops Pipeline

A **DevOps pipeline** is a sequence of automated steps that enables the continuous integration, testing, delivery, and deployment of software applications. It combines development and operations (Dev + Ops) practices to improve the speed, quality, and efficiency of software delivery.

The pipeline automates repetitive tasks and ensures that each change or new feature is thoroughly tested before it reaches production, helping organizations achieve faster releases and higher-quality software.

**Key Stages of a DevOps Pipeline**

A typical DevOps pipeline is composed of several stages, each with its own set of tasks and tools. Here’s a breakdown of the key stages:

1. **Source Code Management (SCM)**:
The pipeline begins with **source code management**, where developers commit code changes to a version control system. These changes trigger the pipeline to start the process.

**Tools**:
— Git (GitHub, GitLab, Bitbucket)
— Subversion (SVN)

2. **Continuous Integration (CI)**:
In the CI stage, code changes are automatically built and tested. This ensures that new code integrates smoothly with the existing codebase. The goal of CI is to detect issues early by running automated tests with every code commit.

**Tools**:
— Jenkins
— Travis CI
— CircleCI
— GitLab CI
