Git/CI/CD

(devops pipeline)

Why Git?

• Decentralized/can commit locally vs requiring connection to centralized server (ala SVN)
• Smaller repository sizes on disk
• Lightweight tags/branches
• Ubiquitous in the open-source source control realm 

Why continuous integration (CI)?

• Offload full-suite testing to somewhere else
• Transparency in tests / builds (prevents "It worked for me")
• Confidence in working deployments
• Forces use of source control

Why continuous deployment? (CD)

• Manual deployment is prone to human error
• Push fixed issues and new features out to customers quickly
• Deprecates need for large monolithic "releases"

Prevent the chaos
