CI/CD Pipeline Basics

Defining CI/CD Pipelines

A CI/CD pipeline is a set of automated steps that help move code from development to production. It combines continuous integration (CI) and continuous delivery or deployment (CD) to speed up software development. The pipeline helps teams:

Improve software quality
Release updates faster
Reduce errors and downtime

Parts of a CI/CD Pipeline

A typical CI/CD pipeline has four main stages:

Stage	Description
Source	Developers write and update code
Build	Code is compiled into a usable form (e.g., Docker image)
Test	Code is checked for quality, bugs, and security issues
Deploy	Tested code is prepared for release to users

Advantages of Using CI/CD

CI/CD pipelines offer several benefits:

Advantage	Description
Faster development	Smaller code changes make testing easier and quicker
Quick market entry	Faster updates help products reach users sooner
Lower risk	Teams can try new ideas with less worry about big failures
Better maintenance	Bugs are found and fixed more quickly
Smoother operations	Regular updates help IT teams manage software better

Core Ideas in Pipeline Orchestration

What Pipeline Orchestration Means

Pipeline orchestration manages and coordinates the steps in a CI/CD pipeline. It automates how code changes move through the pipeline, from development to production. This process helps:

Make the pipeline run smoothly
Cut down on mistakes
Speed up software development

Main Concepts in Orchestration

Here are the key parts of pipeline orchestration:

Concept	Description
Workflow	The order of steps code goes through
Stage	A specific part of the workflow (e.g., build, test)
Task	A single action in a stage (e.g., compile code)
Artifact	Files made by a task (e.g., compiled program)

How Orchestration Differs from Automation

Automation and orchestration are not the same:

Concept	Focus
Automation	Doing single tasks without human help
Orchestration	Managing how tasks work together

Automation is about making individual jobs easier. Orchestration takes this further by overseeing the whole process. It sets up a system to handle all the steps from when code is written to when it's used by customers.
