Term	Kind	Topic	What it is
Warm Pool	pattern	Autoscaling	Pre-initialised instances held in a stopped or standby state so that scaling out skips boot and application warm-up.
Webhook	pattern	API & Integration	An HTTP callback from a provider to a consumer-supplied URL when an event occurs, replacing polling with push.
WebSocket Backplane	pattern	WebSockets & Realtime	A shared publish/subscribe layer letting a message published on one server reach clients connected to a different server.
Workload Class Isolation Compute Separation by Class, Interactive vs Batch Pools	pattern	Data Lakes & Lakehouses	Running interactive, scheduled and batch analytical workloads on separate compute over shared storage, so that a long-running job cannot make an analyst's query unpredictable.
Write-Ownership Boundary Single-Writer Boundary, Authoritative Writer Assignment	pattern	Coexistence Patterns	The line drawn during coexistence that names exactly one system as the writer for each piece of state, placed along business transaction boundaries so that no single transaction has to commit on both sides.
