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
Aspirational and Achievable SLO practice SLI, SLO & SLA The distinction between the reliability a team wishes for and the reliability its current architecture and dependencies can actually deliver.
Journey-Level SLO Per-Journey Availability, User-Facing SLI practice SLI, SLO & SLA Setting reliability targets per user journey rather than per platform or per service, because consequence differs by journey and only a journey-level measurement reflects what a user experienced.
Request-Based and Window-Based SLI metric SLI, SLO & SLA Two ways of computing the same reliability target — counting good events, or counting good time windows — which produce materially different numbers.
SLI, SLO and SLA metric SLI, SLO & SLA The measurement, the internal target, and the external contract — with the error budget as the mechanism that makes the target consequential.
User Journey SLO Critical User Journey, CUJ practice SLI, SLO & SLA Defining reliability targets around what a user is trying to accomplish, measured where the user is, rather than around per-request success rates at the server.
