Git

A distributed version-control system for tracking changes in source code during software development.

Git is a distributed version control system that tracks changes in source code during software development. Created by Linus Torvalds in 2005, Git allows multiple developers to work on the same codebase simultaneously, maintaining a complete history of all changes and enabling branching, merging, and collaboration.

Git stores the complete repository history on every developer's machine, enabling offline work and fast operations. Key concepts include commits (snapshots of changes), branches (parallel lines of development), merges (combining branches), and remotes (connections to shared repositories). Hosting platforms like GitHub, GitLab, and Bitbucket provide centralized collaboration features on top of Git.

In API and serverless development, Git is essential for managing both application code and infrastructure configuration. API gateway configurations, routing rules, and deployment scripts are stored in Git repositories, enabling version tracking and code review. GitOps workflows use Git as the single source of truth for infrastructure state, automatically deploying changes when they are pushed to the repository.
