AI and accelerated-compute workloads have rewritten the assumptions colocation buyers used to rely on, particularly around power density, which now regularly exceeds what older facilities were designed to deliver.
Ask ten infrastructure leaders how they choose a data center and you will get ten different answers. Yet beneath the variety, the same handful of questions tend to decide the outcome.
Why it matters now
Power has overtaken floor space as the binding constraint in most primary markets. Vacancy rates have fallen to record lows, and the practical effect is that capacity — particularly high-density capacity — increasingly needs to be reserved well ahead of when you actually need it.
The market has split in two. Standard enterprise workloads still run comfortably at three to five kilowatts a rack, while accelerated-compute deployments are pushing twenty, fifty, even a hundred kilowatts. Those two worlds are priced and provisioned very differently, and conflating them is a common and expensive mistake.
A practical way to evaluate
Model the whole cost, not the monthly line. Setup fees, cross-connects, bandwidth, growth headroom, and exit terms all belong in the comparison. The cheapest rack rate is rarely the cheapest deployment.
Then shortlist on objective data and validate with your own eyes. Marketplace intelligence is excellent for narrowing the field quickly, but a site visit and a couple of reference calls will tell you things no datasheet can.
Planning for what comes next
Geography is strategy. Where your data physically sits affects latency, sovereignty, and resilience. Spreading critical workloads across regions is no longer just for the largest enterprises.
Term length is a lever worth pulling thoughtfully. Longer commitments unlock materially better rates and, increasingly, priority access to scarce capacity — but only commit ahead if you are confident in the trajectory.
The factors that actually move the needle
Tier classification tells you what a facility was designed to do, not how well it is run. A well-operated Tier III site routinely outperforms a poorly managed Tier IV one on the metric that matters: real-world availability.
Connectivity richness is frequently underweighted. A carrier-neutral facility with a dense ecosystem of networks and direct cloud on-ramps can save more over a contract term than a modest difference in the rack rate ever will.
A short checklist before you sign
- Leave headroom for growth, including higher-density racks down the line
- Ask what happens operationally when a single system fails, not just what the tier rating implies
- Confirm the certifications your industry and customers actually require
- Write down your power, space, and connectivity needs before you talk to anyone
- Map the network ecosystem: carriers, internet exchanges, and cloud on-ramps
The bottom line
The good news is that you do not have to navigate it alone. With the right data and the right guidance, what feels like a daunting decision becomes a structured, confident one.
