- Agglomeration Loop
- The self-reinforcing dynamic by which each new data center makes a location more attractive to the next, dense fiber and peering draw networks, which draw more facilities, which deepen the ecosystem of crews, contractors, and utility relationships. It explains why compute capacity clusters into a few dominant hubs rather than spreading evenly, and why established hubs keep thickening even as they strain.
- Availability Zone
- A failure-independent cluster of one or more data centers within a cloud region, with its own power feeds, cooling, and networking, located far enough from sibling zones to avoid a shared local failure yet close enough for low-latency synchronous replication. Regions typically have three or more, which is what lets customers run applications that survive the loss of an entire zone.
- Capacity Geography
- The spatial pattern of where compute capacity concentrates and where it is moving next, shaped by a stack of partly substitutable advantages: deliverable power, permitting speed, land, climate, fiber density, tax treatment, and proximity to existing gravity. Reading it forward means following the binding constraint, now overwhelmingly power, to the markets where the next wave of capacity will form.
- Cloud Region
- A geographic area in which a provider operates multiple availability zones as a coordinated, resilient footprint. Building one is a multibillion-dollar, multi-year commitment spanning several separately powered sites, so an announcement functions as a demand forecast backed by the provider's own capital rather than a marketing claim.
- Colocation
- Renting space, measured in cabinets, cages, or a few megawatts, inside a multi-tenant facility where power, cooling, and security are shared. It is the fastest, lowest-commitment way to enter a metro or hold interconnection-rich space near a network exchange, but the most expensive per megawatt. Operators use it for speed, edge presence, and optionality rather than for core at-scale capacity.
- Interconnection Queue
- The regulated process and waiting line for connecting a large new electricity load, such as a data-center campus, to the power grid. In the busiest markets it can run several years and may require the utility to build new transmission or substations. It is the dominant timing constraint on self-builds and the main reason capacity migrates toward markets that can energize large loads sooner.
- Owned Build
- A data center that the operator finances, designs to its own standard, and owns, either on balance sheet or through a controlled joint venture. It gives maximum control over power, design, and expansion and the lowest lifetime cost per megawatt, but ties up large capital in a fixed, single-purpose asset for fifteen to twenty years, so operators reserve it for demand they judge durable.
- Wholesale Lease
- A long triple-net lease, typically ten to fifteen years, of a facility a specialist developer finances and builds to the tenant's specification. The tenant avoids sinking capital into the building shell while the developer carries construction and real-estate risk for a contracted yield. It is faster than self-building but costs more per megawatt over the asset's life because the developer's return stacks on top of construction cost.
