What is Continuous Deployment?

Continuous Deployment is the extension of Continuous Delivery where every commit that passes the pipeline goes automatically to production — no human approval required.

How it works

Commit → Build → Tests → Staging → Production (automatic)

There is no button to press. If the pipeline passes, the code is in production. If it fails, the deploy is automatically blocked.

What it takes to do it well

Continuous Deployment demands a solid technical foundation:

• High test coverage — automated tests are the only gate before production
• Feature flags — to decouple deploy from release (code ships to prod, but the feature stays off until ready)
• Observability — monitoring, alerts, and automated rollback to catch regressions fast
• Team trust — confidence in the pipeline, and discipline to act on alerts immediately

Who does it

Companies like Amazon, Netflix, and GitHub deploy dozens or hundreds of times per day using Continuous Deployment. It's the practice that makes that volume possible without sacrificing stability.

When not to use it

Continuous Deployment may not fit when:

• Regulation requires human sign-off before a deploy (e.g., healthcare, finance)
• Test coverage isn't reliable enough to trust the pipeline
• Production bugs are extremely costly and rollback is complex
