A modern data center is one that can support an enterprise’s actual workloads, recover from failures, adapt as demand changes, and measure its energy and resource impacts. That may mean upgrading an owned facility, using colocation or cloud, or combining all three; no single architecture or efficiency target fits every organization.
Start with workload fit, not a preferred architecture
Before choosing where infrastructure should run, map what it must do. Include current and expected compute demand, growth, latency and location requirements, recovery objectives, and any regulatory or geographic constraints. Identify the most demanding workloads as well as the average: a facility that supports ordinary racks may still be unsuitable for a small number of power-hungry cabinets.

Uptime Institute’s 2024 Global Data Center Survey reported an average typical rack density of 8 kW, or 7.1 kW when 11 sites reporting a highest rack density above 50 kW were excluded. These are survey calculations, not recommended design targets. The survey also found that 29% of operators were upgrading existing data hall space to provide power and cooling for higher-density cabinets. That retrofit figure is a respondent result, not a forecast for every facility.
The survey points to a practical planning issue: capacity is not just floor space. A high-density deployment needs a credible path for supplying and removing heat at the cabinet and room levels, and for doing so within the site’s electrical limits. Uptime Intelligence executive director Andy Lawrence said in the institute’s July 2024 survey announcement that increased demand was affecting existing facilities’ power and cooling capabilities and requiring further investment.

Design resilience around failure dependencies
Redundancy matters, but resilience depends on how power, cooling, network, IT systems, controls, and people interact. Map the dependencies that could take down a workload, including shared components that may undermine otherwise redundant paths. Confirm what happens during maintenance, a component failure, a utility interruption, or a recovery event—not only what the design diagram says should happen.
In Uptime Institute’s 2024 survey question about respondents’ most recent impactful outage (n=97), 54% attributed it to on-site power distribution. IT systems and networking together accounted for 23% of impactful outages. These are survey responses about reported incidents, not a universal probability of failure, but they make electrical distribution and the connections between systems essential parts of a resilience review.
Rack-mounted power distribution units can help distribute and monitor power at the rack, but a retail rack PDU by itself cannot prevent outages or replace facility-level electrical design. Assess rack-level equipment as one layer in a documented power strategy, with suitable monitoring, maintenance, and clear ownership of alarms and response.

Include operating practice in the resilience plan
Equipment alone does not determine availability. Uptime Institute reported that four in five surveyed operators believed their most recent significant downtime incidents could have been prevented with better management, processes, or configuration. That is respondents’ assessment, not independent proof of the cause of each incident. For an enterprise, it is a reason to examine change control, configuration management, staff training, maintenance procedures, failover tests, and incident reviews alongside the hardware.
- Define recovery objectives for each workload and verify that the infrastructure and operating procedures can meet them.
- Document power, cooling, network, and control-system dependencies, including shared points of failure.
- Test maintenance and recovery procedures under realistic conditions, then record and address what the tests reveal.
- Make responsibility for monitoring, escalation, and incident response explicit across internal teams and service providers.
Evaluate efficiency across the whole facility
Energy efficiency is not a single equipment choice or a single metric. The U.S. Department of Energy’s Federal Energy Management Program guide covers IT systems and environmental conditions, air management, cooling and electrical systems, heat recovery, and measurement and benchmarking. Its scope reflects the need to assess the interactions between computing equipment and the facility that supports it. The guide also cautions that it cannot prescribe the most energy-efficient design for every data center scenario.

Use that whole-system perspective when evaluating a new build, retrofit, colocation facility, or cloud service. Ask how the proposed design addresses IT utilization, airflow and containment, cooling, electrical losses, and opportunities to reuse heat where there is a suitable source and use. Compare the measurement boundaries and operating assumptions behind efficiency claims; a number without its scope and conditions is difficult to interpret.
Cooling choices must also fit the equipment, site, operating model, and workload. The Uptime Institute Global Data Center Survey 2024 report stated, in its publication context, “The reliability of liquid cooling is, as yet, untested at scale in the field.” This is the report’s assessment at that time, not a current universal verdict on every liquid-cooling deployment. Enterprises considering it should evaluate deployment-specific operating evidence, service arrangements, monitoring, and recovery plans rather than assuming either proven maturity or blanket unsuitability.

Measure sustainability beyond one headline number
Choose a measurement set that helps the organization understand both facility efficiency and its broader resource goals. Power use and power usage effectiveness (PUE) can be useful measures, but they do not by themselves describe water use, energy sourcing, carbon goals, or heat recovery. Confirm which systems and loads are included, how often measurements are taken, and whether data can support the organization’s reporting needs.
In Uptime Institute’s April 2025 sustainability survey results, 79% of owner/operator respondents reported collecting IT or data center power consumption for environmental sustainability purposes, and 72% reported collecting PUE. The corresponding figure for water usage was 45%. In the same survey, 42% of respondents reported an enterprise-wide data center renewable-energy goal and 26% reported an enterprise-wide carbon-free energy consumption goal. The 2025 survey included 974 industry respondents overall; owner/operator response bases varied by question, so these percentages should not be read as results from one identical subgroup.
For procurement, ask a provider what sustainability data it can supply, how the figures are defined, and whether the data covers the service and location being considered. For an owned facility, establish baselines and assign responsibility for collecting, validating, and reviewing the metrics. Water and heat-reuse opportunities deserve explicit attention alongside electricity, where local conditions and the facility design make them relevant.

Choose where workloads run—and revisit the choice
Placement is a workload decision, not a once-and-for-all choice between “on-premises” and “cloud.” Owned infrastructure, colocation, cloud, and hybrid arrangements may each suit different workloads or stages of growth. Compare them using the same requirements: workload and density needs, latency, available power and cooling, redundancy and recovery, efficiency and sustainability data, staffing, deployment timing, geographic or regulatory constraints, and total cost.
Uptime Institute’s 2024 survey estimated that 55% of surveyed organizations’ IT workloads were hosted off-premises. Respondents forecast that share would reach 58% by 2026; this was a forecast in the 2024 survey, not a verified measurement of the 2026 outcome. The result supports planning for mixed placement, but it does not establish that off-premises hosting is best for a particular enterprise.
A practical comparison process
- Classify workloads. Record performance, latency, density, growth, availability, recovery, location, and compliance requirements for each workload or workload group.
- Set minimum infrastructure conditions. Specify the power, cooling, network, redundancy, monitoring, and recovery capabilities needed to meet those requirements.
- Assess operating capability. Determine whether the enterprise and each prospective provider can staff, maintain, test, and manage the relevant environment, with clear incident and change responsibilities.
- Request comparable evidence. Ask for capacity and service details, resilience arrangements, measurement boundaries, sustainability data, deployment timing, and costs using consistent assumptions.
- Place workloads individually. Select owned, colocation, cloud, or hybrid environments according to fit rather than applying one placement rule to every system.
- Review as conditions change. Reassess placement when workload demand, facility capacity, service terms, operating capability, or sustainability requirements change.
The comparison is only as sound as its assumptions. A provider’s available capacity, measurement approach, service commitments, and deployment schedule should be verified for the specific location and workload rather than inferred from a general product description.
What to put in an enterprise requirements brief
A concise brief gives IT, facilities, procurement, and sustainability teams a shared basis for evaluating options. Include the following before soliciting proposals or approving a major upgrade:
- Workload profiles, expected growth, peak rack density, latency, and placement constraints.
- Power and cooling capacity, resilience requirements, dependencies, recovery objectives, and testing expectations.
- Efficiency, water, energy-sourcing, heat-reuse, and sustainability reporting requirements.
- Staffing and operating responsibilities, including maintenance, change control, monitoring, and incident learning.
- Deployment schedule, geographic and regulatory constraints, and a total-cost comparison based on consistent assumptions.
The goal is not to specify a fashionable architecture. It is to make capacity, resilience, efficiency, reporting, and operational requirements explicit enough that each proposed environment can be tested against the same workload needs.
