Progressive delivery

By Updated

Releasing a change to a small, growing share of real traffic in stages (shadow, pilot, canary, general availability), each with rollback criteria registered before it starts and a tested path back to the previous version, so evidence about live behaviour arrives before full exposure. For AI systems it covers model, prompt, corpus and vendor-version changes alike.

  • Blue-green deployment

    Two identical production environments with traffic switched between them, so a release can be rolled back by switching back.

  • Canary release

    A partial, time-limited deployment of a change to a small share of production traffic, evaluated against a control group before the rollout continues.

  • Rollback criteria

    The conditions, written into the rollout plan before a release stage starts, under which the pipeline returns to the previous version automatically: a floor…

  • Shadow deployment

    A release stage in which a new model or system receives live inputs but its outputs are not used, so its behaviour on real traffic can be compared with the…

  • Version pinning

    Fixing, in the registry entry, the exact versions of the model, prompts, retrieval corpus and guardrails a deployed system uses, so what ran is known and any…

  • AI system

    For governance, the object the AI definition brings into scope.
