Term	Kind	Topic	What it is
Availability Calculation	concept	Reliability & Resilience	Deriving a system's availability from its components, remembering that dependencies in series multiply.
Redundancy	concept	Reliability & Resilience	Having more instances of a component than the load requires, so that failures can be absorbed without loss of service.
Service Level Agreement SLA	concept	Reliability & Resilience	A contractual commitment about service level, with a defined remedy — usually a service credit — when it is missed.
Static Stability	concept	Reliability & Resilience	The property that a system keeps working on its existing state when its control plane or dependencies are unavailable, rather than needing them to keep running.
