Ultimate Guide On How To Choose A Data Center

Nevermore has data been as much of a priority as it is today for modern businesses. Information, sensitive data, customer and business details, software, and much more are all essential to businesses. A lot is riding on businesses to handle their data properly and store it in a secure, ironclad location.

Data centers are often the solution for many companies, both large and small. However, shopping for a data center can be an overwhelming task and not all are created equal. That’s why it’s so important for businesses to research data centers and make the most informed decision. When you do so, you can have peace of mind that you’ve selected the best data center for your needs.

To fine-tune your data center selection, consider the following factors.

Location

The first and arguably most important, factor to consider when shopping for a data center is the location. You want to ensure it is located either in an area that is not prone to natural disasters or in a location that has rock-solid contingency plans in the event of a natural disaster, such as being located on own separate power grid.

Also, you want to be sure that the data center’s proximity to your employees is near enough so that emergency repairs are not held up by long commute times. Ideally, the data center you choose should have multiple routes that your team can take in the event of road closures, flooding, and other unforeseen circumstances. Choosing an easily accessible data center saves both time and money in the long run.

Connectivity

Using a data center gives businesses access to a variety of connectivity options that they may not otherwise have had. When evaluating data center options, be sure to ask questions about their interconnectivity options. Often a “carrier-neutral” data center is the ideal choice, as it allows customers access to a variety of internet and cloud service providers, whereas single-carrier facilities only allow for connectivity to one vendor, which can increase costs and be limiting. Even if a facility advertises that they feature multiple carriers, it’s a good idea to ensure your data center’s options are robust and not limited to just a handful of options. For cloud-based connections, ask the data center if they provide cross-connection so you can establish a direct connection between your servers and your cloud provider’s servers.

Reliability & Emergency Contingency Plans

When shopping for a data center, the provider’s reliability and contingency plans for emergencies should be a top consideration. The data center you choose should have a proven record of uptime ranging from 99.999% to 100% as well as a backup power source, redundant systems, and proper cooling and ventilation.

Staff

For the best possible experience, choose a data center that always has both a NOC (Network Operations Center) staff as well as engineers on-site. This allows for NOC staff to handle daily tasks while engineers support the infrastructure of the data center.

Reputation

As with any business vendor decision, doing your research on a data center’s reputation throughout the industry is an important step. Check with current and former clients to determine how the data center handled any issues and whether their claims regarding security, reliability, and uptime are accurate.

Approach to Partnership

Among knowing that the data center has a solid reputation, it’s important to assess how the data center and their staff approach their relationships with clients. Check reviews and speak with current or former clients of the data center to determine if they are consistently responsive and how they handle customer service issues. A data center should have a vested interest in the success of your business and should look at every one of their clients like a valued partnership. Many service agreements for data centers are long-term, so it’s vital to make sure you’re working with people who you can build a strong and positive working relationship with.

SLA (Service Level Agreement) Details

Agreeing to partner with a data center is a big commitment. That’s why you should read over the data center’s SLA, or Service Level Agreement, in great detail to understand their outlined guarantees, costs, and other terms. Data centers’ SLAs vary, so check their guarantees related to uptime, response time, security features, bandwidth allocation, and what the provider promises in the event they fail to meet those guarantees.

Accommodations

Never underestimate the importance of having client workspaces available at a data center. It may not seem like an important consideration when doing the first-time walkthrough, but in the event your staff will need to be on-site for any reason, your team must have space where they can work comfortably and with proper connectivity access points.

Your Goals – Current and Future

When shopping for data centers, be sure to inform the managed services provider of your goals, both currently and in the future. For example, if you have a dedicated date set aside to go live, you need to ensure that the data center can accommodate the move for you by that date. Also, if you have plans for business growth or changes, be sure the data center offers options that make them a flexible and scalable choice for the future.

What are the most important factors to consider when choosing a data center?

The most important factors are location, reliability and uptime, power and cooling, network connectivity, security, and room for future growth. Location affects latency, access for your staff, and exposure to regional risks such as severe weather or unstable power grids. Reliability and uptime are typically measured through SLAs and tier ratings, where Tier III or IV facilities and uptime commitments above 99.98% are common choices for critical workloads. Power, cooling, and connectivity determine whether the facility can support your current and future density requirements, especially for AI and high‑performance computing. Strong physical and network security, plus clear paths to expand space and power as you grow, round out the core decision criteria.

Why does data center location matter so much for performance and risk?

Data center location influences latency, user experience, regulatory compliance, and resilience against natural and infrastructure‑related threats. Placing workloads closer to major customer bases, cloud on‑ramps, and network exchange points reduces round‑trip time and improves application responsiveness. At the same time, regions with stable power grids, low natural‑disaster risk, and supportive zoning rules lower the likelihood of prolonged outages or forced relocations. In 2026, many organizations also weigh access to renewable energy and climate resilience, as extreme weather and energy prices put more pressure on long‑term site selection.

What should I look for in a data center’s reliability, uptime, and SLAs?

For reliability, you should look at both the facility design (often expressed as a Tier rating) and the provider’s historical performance and SLA terms. Uptime commitments around 99.982% or higher, backed by redundant power feeds, backup generators, and N+1 or better cooling, are common benchmarks for mission‑critical environments. A strong SLA clearly defines uptime metrics, response times, maintenance windows, and credits in the event of service failures. Reviewing incident histories, customer references, and any published operational metrics helps verify that the provider consistently meets or exceeds those promises.

How important are security and compliance when selecting a data center provider?

Security and compliance are essential, because you are entrusting the physical and network environment that protects your critical data and systems. At a minimum, you should expect layered physical security (access control, surveillance, on‑site staff), robust network protections, and well‑documented incident‑response processes. Compliance certifications such as SOC 2, ISO 27001, PCI‑DSS, HIPAA, or GDPR alignment demonstrate that the facility has undergone independent audits and follows recognized standards. For regulated industries, these controls often form part of your own compliance evidence, so gaps at the data center level can create downstream risk for your organization.

How can I be sure a data center will scale with my business over the next 5–10 years?

To ensure scalability, evaluate a data center’s available space, power capacity, network diversity, and track record of upgrading infrastructure without disrupting customers. Ask about current and planned power densities per rack, expansion space for additional cabinets, and whether the facility supports higher‑density deployments for AI and advanced analytics. Connectivity options—including multiple carriers, cloud on‑ramps, and internet exchange access—should be sufficient to support more traffic and hybrid architectures as you grow. Finally, review contract flexibility, upgrade paths, and the provider’s investment roadmap so you know they intend to keep the site modern and aligned with emerging data center trends.
