How to Choose a Data Center: 5 Key Factors
- Updated: March 18, 2026
Your data center is the foundation of your IT operations. When it fails, everything fails—applications go down, productivity stalls, and the financial impact adds up fast. Making the right choice upfront protects your business from those consequences.
This guide covers five key factors to evaluate during the data center selection process. Whether you’re exploring colocation, hybrid data center solutions, or managed data center services, these criteria will help you make a confident, well-informed decision.
Key Factor #1: Location
Where your data center sits has a direct impact on performance, availability, and risk exposure.
Proximity reduces latency. The closer your data center is to your primary user base, the lower the latency. Lower latency means faster application performance and a better experience for employees and customers alike.
Geography affects risk. Avoid regions with a high frequency of natural disasters — floods, earthquakes, and severe weather events all threaten uptime. Look for facilities in areas with redundant power grids, backup generation, and access to multiple internet infrastructure providers. These aren't nice-to-haves. They're the baseline for reliable operations.
Key Factor #2: Reliability
Downtime is expensive. For a mid-size organization, the average cost of a single hour of downtime is $300,000. That number makes reliability a non-negotiable evaluation criterion.
Uptime SLAs matter. Look for providers that offer 99.999% uptime—known as "five nines." That translates to no more than 5.26 minutes of unplanned downtime per year. Get that commitment in writing through a formal Service Level Agreement.
Redundancy protects you when things go wrong. Reliable data centers build in backup power through on-site generators and feeds from multiple utility grids. Redundant cooling systems prevent overheating that can cascade into larger failures.
Verify the track record. Ask for references. Review facility certifications. Talk to existing customers. A provider's history of actual uptime tells you more than a spec sheet ever will.
Key Factor #3: Security
Physical security starts at the perimeter. Look for multi-factor access controls, 24x7 surveillance with intrusion detection, and physical barriers like mantrap entryways and security cages. These layers make unauthorized access significantly harder.
Data security requires verifiable standards. Encryption at rest and in transit should be standard. Depending on your industry, compliance with frameworks like PCI DSS or HIPAA may be required—confirm the provider holds the relevant certifications before signing anything.
Disaster recovery plans reveal operational maturity. Ask every provider for their documented recovery plan. How quickly can they restore data and applications after a power outage, natural disaster, or security incident? A solid plan—and evidence it has been tested—separates professional operations from ones flying without a safety net.
Key Factor #4: Network
Avoid single points of failure. A data center connected to a single network carrier is a liability. Look for facilities with multiple high-bandwidth connections from different providers. If one path goes down, traffic should route seamlessly through another.
Cloud connectivity affects application performance. If your environment includes cloud-based workloads—and most do —direct interconnection with major cloud providers and internet exchanges reduces latency and improves reliability for those applications.
Plan for growth. Your bandwidth requirements today won't be the same in three years. Choose a provider with a flexible, scalable network infrastructure that can accommodate expansion without forcing a migration.
Key Factor #5: Cost
Demand transparent pricing. Request a full breakdown of costs before any commitment: monthly fees, power consumption charges, bandwidth pricing, and any additional service fees. Providers who hesitate to share this detail upfront are a warning sign.
Evaluate total cost of ownership, not just the line-item price. The initial quote rarely reflects the full picture. Factor in power and cooling costs, ongoing maintenance, hardware refresh cycles, and potential scaling costs. A thorough Total Cost of Ownership (TCO) analysis gives you an accurate view of what you'll actually spend—and helps you compare options on equal footing.
The Case for Managed Data Center Services
Running a data center is operationally demanding. For many organizations, shifting that responsibility to a managed services provider (MSP) is the smarter move.
Here's what managed data center services deliver:
- Freed IT capacity. Your team stops spending time on maintenance and monitoring and starts focusing on initiatives that drive business outcomes.
- Proactive uptime management. MSPs build their practice around reliability. Proactive monitoring and maintenance reduces downtime and keeps critical applications running.
- Stronger security posture. MSPs stay current on evolving threats, maintain compliance certifications, and continuously monitor for vulnerabilities — so you don't have to.
- Flexible scaling. Whether your business is growing fast or right-sizing, managed services let you adjust resources without the overhead of managing infrastructure changes yourself.
