Terminology

2205 terms, tools, patterns and metrics an architect is expected to use precisely. Each one gets a short explanation of what it is, and — where it matters — what it is commonly confused with. Search filters as you type; the column headers sort.

Term Kind Topic What it is
Blast Radius Staging Graduated Rollout, Progressive Shedding practice Failover Applying a change or a traffic shift in increasing increments gated on health, so that a wrong decision affects a bounded population before it affects everyone.
Failover pattern Failover Switching to a standby when the primary fails — where detection, fencing and the decision to automate are harder than the switch itself.
Failover Orchestration pattern Failover The sequence of detection, decision, promotion and traffic redirection that moves service from a failed component to a healthy one.
Failover Propagation Delay Client Convergence Time, Failover Tail metric Failover The interval between a failover completing on the server side and the last client actually using the new location, which is usually the larger part of the recovery time users experience.
Health Check Depth Shallow vs Deep Health Check, Dependency Health Check concept Failover How much of a service's dependency graph a health check consults, which determines whether the check reports an independent fault or a shared one that every instance will report at the same moment.
