Term Kind Topic What it is
Admission Policy pattern Policy as Code A rule evaluated at the moment a resource is created or changed, which rejects the request rather than reporting on it afterwards.
Expand-Contract Migration pattern Database Migration Under CD Changing a schema in additive steps that keep old and new code both working, so deployment and migration never have to be simultaneous.
Pipeline Fan-Out pattern Pipeline Architecture Splitting independent verification work to run in parallel, bounded by what genuinely has no ordering dependency on anything else.
Reconciliation Loop pattern GitOps A controller that continuously compares declared state with actual state and acts to close the gap, replacing deployment as an event with convergence as a property.
Release Ring pattern Progressive Delivery An ordered cohort of users a change reaches before the next one, chosen so that early rings would notice a fault and tolerate it.
