What Is Continuous Deployment (CD)? | Vantage
Continuous Deployment Continuous deployment (CD) is the practice of automatically deploying every code change that passes the automated test suite to production. There is no manual approval step between passing tests and reaching users. Every successful build is a production release.
Why continuous deployment matters
CD reduces the time between writing code and getting user feedback from weeks to hours or minutes. Smaller, more frequent deployments reduce risk (each change is small and easy to debug), enable faster iteration, and keep the product continuously improving.
How it works
A developer merges code. CI runs automated tests. If all tests pass, the deployment pipeline automatically deploys to production. The deployment typically follows a progressive rollout: deploy to a canary server, monitor for errors, then roll out to all servers. If errors are detected, the deployment automatically rolls back.
Common mistakes
Deploying without sufficient automated tests (CD is only safe with high test coverage)
Not monitoring production after deployments (errors may not appear immediately)
Not having a fast rollback mechanism (if something breaks, you need to undo quickly)
Confusing continuous deployment with continuous delivery (delivery deploys to staging, not production)
Not using feature flags with CD (large features need gradual rollout, not instant full deployment)

How Vantage relates
Vantage generates tickets that include deployment and rollout strategies. When tickets specify progressive rollout (behind feature flags with monitoring), the engineering team has a clear plan that aligns with CD practices.
