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
Connection Migration Session Continuity, Seamless Handover	concept	WebSockets & Realtime	Keeping a logical session alive when the underlying network path changes - either in the transport, or reconstructed by the application after a reconnect.
Fan-Out Amplification Broadcast Multiplication, Subscriber Amplification	concept	WebSockets & Realtime	The property that one input event becomes as many output events as there are subscribers, making the workload proportional to audience size rather than to event rate - and the reason broadcast paths cannot sha…
Reconnect Storm Thundering Herd on Reconnect, Connection Stampede, Recovery Amplification	concept	WebSockets & Realtime	The synchronised burst of clients re-establishing connections after a disruption, which is far more expensive than steady-state traffic and routinely turns a brief network fault into a prolonged self-sustainin…
Server-Sent Events SSE, EventSource	protocol	WebSockets & Realtime	A one-way streaming protocol over plain HTTP in which the server pushes text events to the client on a long-lived response.
WebSocket Backplane	pattern	WebSockets & Realtime	A shared publish/subscribe layer letting a message published on one server reach clients connected to a different server.
WebSockets	protocol	WebSockets & Realtime	A persistent bidirectional connection over HTTP — the right tool for server-initiated updates, and a stateful component in an otherwise stateless architecture.
