Terminology

2225 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
Conflatable Classification Superseding vs Discrete Events, What May Be Dropped	practice	Device Telemetry at Scale	Explicitly classifying each telemetry stream as superseding or discrete, because conflation is the correct overload behaviour for one and silent data loss for the other.
Device Telemetry at Scale	concept	Device Telemetry at Scale	The volume problem created by many devices each emitting small frequent messages, where the answer is filtering at the edge rather than ingesting everything.
Edge Aggregation	pattern	Device Telemetry at Scale	Summarising or filtering telemetry at the device or gateway so that only what is needed leaves, which is usually the difference between a viable and an unaffordable design.
Fleet Reconnection Storm Device Thundering Herd, Synchronised Reconnect, IoT Recovery Surge	concept	Device Telemetry at Scale	A synchronised burst of devices re-establishing connections after any disruption, which is far more expensive than steady-state traffic and routinely turns a brief platform blip into a prolonged outage.
Per-Device Series Budget Fleet Series Count, Device-Tag Cardinality Limit	metric	Device Telemetry at Scale	The number of distinct metric time series a fleet creates - series per device multiplied by device count - which decides observability cost long before data volume does, and which determines whether per-device…
