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
Backhaul Cost per Device-Day Bytes per Device-Day, Per-Device Data Budget	metric	Constrained Protocols	The bytes a single device sends and receives in a day multiplied by the price of the link - the figure that converts a sampling decision into a line in the connectivity contract.
Exception Path Frequency Normal Exceptions, Physical Divergence Rate	metric	Physical-World Failure Modes	The rate at which physical operations diverge from the system's model - a business metric to be managed rather than a defect rate to be eliminated, and the input to how the exception path should be resourced.
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…
Radio Wake Budget Transactions Per Day Budget, Wake Count Budget	metric	Constrained Protocols	The number of radio wakes a device can afford per day at its target battery life - the planning number that decides protocol and batching choices, because energy is spent per transmission rather than per byte.
Remote Resolvability Issues Fixable Without a Visit, Field Visit Rate	metric	Fleet Management	The proportion of device issues that can be diagnosed and resolved without a physical visit - a design-time property that determines the operating cost of a fleet for its entire life.
