Data centers are critical infrastructure for modern technology companies. They house servers, storage, and networking equipment that support online services. With rising demand for cloud computing, video streaming, and other bandwidth-intensive applications, data centers are growing rapidly. But where are they typically located?
Factors Influencing Data Center Locations
Several factors go into choosing data center sites:
Access to Inexpensive Electricity
Data centers use massive amounts of electricity to power and cool servers. To reduce operating costs, companies seek locations with inexpensive electricity. Hydroelectric power and energy market deregulation make some regions appealing. Cisco estimates data centers will consume up to 25% of worldwide electricity by 2025.
Network Connectivity
Data centers must connect to major metro areas and other data centers. Proximity to internet backbone infrastructure and fiber optic networks is essential. Access to multiple network service providers helps ensure redundancy.
Cool Climate
Servers generate substantial heat. Cooler climates reduce cooling costs, but temperatures cannot fluctuate too drastically. Humidity control is also critical to prevent server corrosion.
Physical Security
Data centers contain sensitive intellectual property and personal data. Strict physical security protections like fences, guards, video surveillance, and access control systems help thwart security breaches.
Land Availability
Hyperscale data centers require substantial real estate, often 50+ acres. Locations near metropolitan areas with affordable land enable growth. Some companies opt for rural areas with abundant open space.
Business Operating Costs
Companies favor regions with lower taxes, utility costs, and labor expenses. Tax incentives offered by local governments also factor into location decisions.
Proximity to Customers
Latency refers to delay in data transmission. To provide rapid services, providers situate data centers near major population hubs and end users. Being closer improves the customer experience.
Popular Data Center Geographies
Certain countries and regions have become go-to destinations for data centers:
United States
The U.S. is home to some of the largest hyperscale data centers due to high internet usage, demand for cloud services, and technology innovation. Northern Virginia has the highest concentration of data centers globally with 70% of internet traffic flowing through Loudoun County. Cheap power, land availability, and proximity to the eastern seaboard make this an ideal location.
Other major data center hubs reside near San Francisco, Los Angeles, Phoenix, Dallas, Chicago, Atlanta, New York and central Florida. States like Iowa, Oregon and North Carolina also appeal to data center developers.
China
China has seen rapid growth in internet access and cloud adoption. Major metro areas like Beijing, Shanghai, Shenzhen and Guangzhou house extensive data center infrastructure. While China has high demand, there are challenges around reliable electricity and network connectivity.
Western Europe
Amsterdam, Frankfurt, London, Paris and Dublin are key European data center clusters. Factors like climate, network density, renewable energy, and digital economy strength work in their favor. Ireland has attracted substantial data center investment.
Japan
Tokyo and Osaka are major hubs, given Japan’s advanced broadband infrastructure and tech-savvy population. In the wake of the Fukushima disaster, fears around earthquakes and nuclear power outages persist.
Singapore
Singapore has established itself as a global data center leader due to robust internet infrastructure, political stability, low taxes and commitment to R&D. Its tropical climate also permits natural cooling. Major providers operate large facilities there.
Australia
Australia benefits from a cool climate, stable government and attractive commercial operating conditions. Melbourne and Sydney lead for data centers. Undersea cables provide high-speed connectivity to Asia.
Brazil
Sao Paulo’s strong connectivity, growing cloud adoption and inland location make it an appealing hub for Latin America. Hydroelectric power meets high electricity demands. Other sites are emerging too.
How Companies Select Data Center Sites
Selecting data center locations involves in-depth research and planning. Critical factors include:
Power Resources
Companies evaluate electricity costs, long-term availability and reliability, proximity to substations, and options for backup power like on-site generators. Renewable energy access is a plus.
Network Connectivity
Fiber optic infrastructure and network density allow data centers to efficiently route traffic globally. Carrier-neutral facilities provide access to multiple ISPs.
Cooling Efficacy
From temperature and humidity averages to seasonal shifts, detailed climate analysis guides cooling designs. Some sites utilize outside air, evaporation or chilled water systems.
Geologic Stability
Earthquake and flood risks are evaluated to avoid disruptions. Sites not prone to natural disasters fare better. Sandy soil also poses challenges for construction.
Land Procurement
Companies prefer shovel-ready sites with flexible zoning allowances. Transportation access for construction and operations is vital too. Tax incentives may further enable development.
Existing Infrastructure
Proximity to transit networks, construction resources and a skilled workforce eases data center build-outs. Nearby housing and amenities help attract talent as well.
Security Conditions
Political stability, low crime rates, and limited terror threats provide security assurances. Customs processes must allow timely equipment delivery too.
Here is a table summarizing the key site selection factors:
| Factor | Considerations |
|---|---|
| Power | Cost, reliability, renewable sources |
| Connectivity | Fiber infrastructure, network density, carrier options |
| Climate | Cooling efficiency, temperature stability |
| Geologic | Earthquake, flood and wind risks |
| Land | Shovel ready, permits, tax incentives |
| Infrastructure | Transportation access, construction resources, workforce housing |
| Security | Political stability, crime rates, terrorism risks |
How Companies Balance Data Center Locations
To manage risk and provide reliable services, major cloud platforms utilize a distributed global data center strategy:
Latency Reduction
Data centers in key metro areas reduce latency for regional customers, improving application performance.
Business Continuity
A network of sites prevents service disruptions if any single data center goes offline due to outages or disasters.
Compliance
Data sovereignty laws sometimes mandate local data storage. Regional data centers help meet compliance needs.
Efficiency
Localized data centers allow providers to match resources with demand across time zones. Applications can transfer data quickly within the network too.
Microsoft Azure, Amazon Web Services (AWS) and Google Cloud utilize a balanced data center approach:

Data Center Location Trends
The booming data center market will increasingly expand beyond major hubs:
New Geographic Regions
Untapped international markets offer incentives for data center growth to serve emerging digital economies. Examples include Sweden, Denmark, Norway, Switzerland, South Africa, United Arab Emirates, Saudi Arabia, India and Southeast Asia.
Secondary Markets
Land constraints and higher costs are pushing growth to smaller metro areas with affordable resources, including renewable energy and tax breaks.
Edge Computing
Placing micro data centers closer to end users reduces latency. 5G and IoT advances will drive more distributed edge data centers.
Alternative Models
Floating data centers on barges or decommissioned oil rigs leverage nearby seawater for cooling. Well-connected urban sites like old factories are also being repurposed.
Sustainability
Public scrutiny over data center energy use is increasing pressure for renewable power. Hydroelectric, wind and solar growth make more regions viable.
Conclusion
Data centers form a strategic backbone for our digital economy. While early facilities clustered in areas like Silicon Valley, northern Virginia, and Shanghai, today’s data center landscape is diversifying. Companies are weighing variables from climate and electricity to networks and incentives to build global platforms leveraging the ideal locations. As data demands multiply, we can expect to see innovative new data center models and sites emerge.
