    6 Reasons Why California Is a Great Location for Data Centers

    Many factors make California an ideal location for data centers, from its place in the world’s fourth-largest economy to its deep technology and connectivity base. Here are a few we’d like to spotlight.

    California’s Economy is Huge

    California’s economy continues to grow. In 2024, California’s gross domestic product reached approximately $4.1 trillion, and the state ranked as the fourth-largest economy in the world. California’s economy also grew 6.0% in nominal terms in 2024. Locating your data center in California gives you proximity to a large potential customer base, with the state home to about 39.4 million residents.

    California is also home to many major technology companies, including Apple, Meta, Google, and NVIDIA. Because the state has a broad mix of technology, advanced manufacturing, logistics, and life sciences activity, data centers can conveniently serve a wide range of businesses and customers.

    California Offers Many Data Centers

    California has a thriving data center market that serves many global companies. More than 289 data centers are spread across 33 markets within the state. Some popular operators with California facilities include DataBank, Evocative, Centersquare, Colocation America, and CoreSite.

    California is also home to many of the country’s largest data center markets. For example, businesses consistently turn to Santa Clara with 64 facilities, Los Angeles with 58, San Jose with 47, San Francisco with 11, and San Diego with 14 for colocation and interconnection options. Because of the state’s large data center footprint, customers needing colocation services can choose facilities that closely match their budget and needs.

    California Occupies a Strategic Location

    Located along the Pacific Coast, California is a logical base for U.S. companies wanting to connect to businesses in Asia, Mexico, and Canada. California’s ports serve as the nation’s premier gateway for international trade, handling 40% of all U.S. containerized imports, while Los Angeles data centers are described as a strategic meeting place for U.S. and Asian markets. It is also home to major cities like San Francisco, Los Angeles, and San Diego.

    Other major U.S. markets with strong connectivity to California cities include Las Vegas, Phoenix, Portland, Denver, and Salt Lake City. Current long-haul network routes link California metros with these western hubs, including a Denver-to-San Jose route via Salt Lake City and Reno and multiple Los Angeles to Phoenix and inland western paths. If your business wants to serve customers in these locations, consider choosing a colocation partner within California.

    California Has Excellent Network Connectivity

    California has many fiber optic networks and service providers. Major public cloud platforms maintain California regions, local zones, or data center presence, including AWS Local Zone in Los Angeles, Google Cloud’s Los Angeles region, Oracle Cloud’s US West (San Jose) region, Azure’s West US region in California, Alibaba Cloud’s US (Silicon Valley) region with 2 availability zones, Tencent Cloud’s Silicon Valley region with 2 availability zones, and IBM Cloud data centers in San Jose.

    Furthermore, many undersea internet cables land in California. This network infrastructure allows data centers in the state to serve a wide range of customers from around the globe. These include:

    • JUPITER: This cable system links Los Angeles with Japan and the Philippines and launched with an initial design capacity of 60 Tbps.
    • SEA-US: The SEA-US system links Los Angeles with Hawaii, Guam, the Philippines, and Indonesia.
    • Southern Cross NEXT: This system connects Los Angeles with Sydney and Auckland and supports 72 Tbps of design capacity.
    • Curie: Google’s Curie submarine cable connects Los Angeles to Valparaiso, Chile, with a branch to Panama and a total design capacity of 72 Tbps.

    Data centers in California give colocation facilities a high level of connectivity, helping them provide fast and reliable services to their customers.

    California Has a Highly-Skilled Workforce

    California is the most populous state in the U.S. and the third-largest by area. Because the state has a dense population and one of the world's largest economies, demand for data centers remains high across both businesses and consumers. The state is also home to many leading universities that provide training in computer science, information technology, and related technical fields, including the University of California system and Stanford's Computer Science Department.

    With more than 39.35 million residents, data centers can access the workforce they need to run their businesses over the long term. California also continues to attract talent from around the world. Foreign-born residents made up 27.0% of the state's population in 2020–2024, and the California Department of Finance said international immigration posted a gain of 260,000 people in fiscal year 2023–24, the highest level since 2018. This broad labor pool adds depth to California's technology workforce.

    California Leads in Renewable Energy

    California is a leader when it comes to renewable energy. The state's government developed the Renewables Portfolio Standard to increase the share of green energy in the electricity mix, and California plans to reach 60% renewable retail electricity sales by 2030 and 100% carbon-free electricity by 2045. (cpuc.ca.gov)

    As such, the state continues to draw more power from sources like solar and wind to reduce its reliance on fossil fuels. In 2024, clean energy resources accounted for 62% of California's power mix, while behind-the-meter solar capacity exceeded 17,400 MW. Consequently, data centers in California can take advantage of green energy initiatives to match their sustainability goals and gain wider access to renewable power. (California Energy Commission)

    The California power grid is expected to experience tremendous growth. State data released in June 2025 showed that California added nearly 7,000 MW of new clean energy capacity in 2024, bringing total new grid resources added over the past five years to more than 25,000 MW. The state also expects more than 75,000 MW of new clean energy capacity to come online by 2040. (gov.ca.gov)

    Los Angeles

    Los Angeles has been a major market for data centers since the early rise of the internet. As one of the most technologically developed cities in the U.S., Los Angeles and its neighboring suburbs remain one of California's largest data center clusters, with 72 data centers listed across the market. LA is also home to major subsea connectivity, with multiple subsea cables at One Wilshire opening a gateway to the global marketplace, while the city's broader cable infrastructure continues to support links from the U.S. to Asia-Pacific and Latin America. (datacentermap.com)

    This strong connectivity allows data centers in the city to serve a diverse range of customers with resilient international network access. Elsewhere on California's Central Coast, in San Luis Obispo County, the Grover Beach Cable Landing Station remains an important fiber-optic landing point. That station is a terminal for the PC-1 Network, which Pacific Crossing says delivers the shortest route and lowest latency between Asia and the U.S. with high reliability. (Submarine Networks)

    With a metro GDP of more than $1.295 trillion and a population of about 12.93 million, Los Angeles remains a strong business environment for data centers. (FRED)

    San Francisco 

    With a population of nearly 827,526, San Francisco is part of one of the larger regional markets for data centers and service providers in the United States. The broader San Francisco Bay Area data center market has 164 facilities, 66 providers, and ranks 9th among U.S. markets.

    The city attracts companies from different industries and remains a major technology and AI hub. Furthermore, San Francisco is strategically close to other Bay Area data center markets like Oakland, Silicon Valley, and San Jose.

    More than one-quarter of the region's employment is still tied to the technology sector. Joint Venture Silicon Valley reports that the tech sector accounted for 28% of total employment, and its current regional data tracks Silicon Valley and San Francisco together as a major center for tech talent and major employers. Because of this concentration of tech workers, businesses in San Francisco can access the employees they need to keep their data centers running.

    Sacramento

    Sacramento, the capital of California, remains a promising market for data centers in the United States. The city has 22 data centers listed across the local market, which gives businesses a solid range of colocation options.

    Sacramento is also located in Northern California, within driving distance of the Bay Area and Silicon Valley, which keeps it close to major global and regional technology markets.

    Another factor that attracts data centers to Sacramento is its relatively favorable natural hazard profile. Major operators such as NTT describe Sacramento as a seismically stable alternative to more fault-active Bay Area locations.

    The city is still exposed to flood risk, and Sacramento provides public flood maps and flood preparedness resources for businesses and property owners.

    Furthermore, data centers in Sacramento have access to relatively affordable energy supplies. SMUD says its customer bills remain among the lowest in California and average more than 50% below neighboring investor-owned utilities.

    The utility also reports that its power supply was about 62% carbon free in 2024, and its 2030 Zero Carbon Plan remains in place. That combination gives Sacramento colocation facilities access to a cleaner power mix while keeping electricity costs more competitive than in some nearby California markets.

    San Diego

    There are many reasons why San Diego remains a strong data center market in California. The city is strategically positioned on the Pacific Ocean and the U.S.-Mexico border, which makes it well placed for companies that want access to international markets, especially in Latin America and the Pacific Rim. San Diego is also directly tied into cross-border digital infrastructure, with providers offering connectivity into Baja California through two independent routes via San Ysidro and Otay Mesa.

    Secondly, the city's stable weather helps colocation facilities and customers maintain steady operations. The National Weather Service says thunderstorms in San Diego are rare, averaging about three a year, and that sunshine is plentiful. Earthquake risk is still a factor, however. The city maintains a Seismic Safety Study to evaluate local geologic hazards, and the U.S. Geological Survey says Southern California has one of the highest earthquake-risk profiles in the United States.

    Irvine

    Irvine has nearly 318,683 people and is one of the largest cities in Orange County. Because it is strategically located in central Orange County, approximately halfway between Los Angeles and San Diego, the city continues to attract businesses that want access to both markets. Irvine also has a business-friendly environment that makes it easier for data centers to grow. For example, the city's business initiatives include a utility users tax of 1.5% with a maximum pre-paid cap of $5,000 per year, planning and zoning support, and permit processes that can involve concurrent review for some commercial projects. The city's 2024 Irvine Innovation Economy Report also points to a well-educated workforce and strong local government support.

    In addition to this, Irvine and the Greater Irvine Chamber continue to publish economic development resources such as the 2024 Irvine Innovation Economy Report, which looks at growth opportunities through 2030. The city also continues to plan actively for natural hazards. Irvine maintains wildfire preparedness resources and public flood insurance and flood map information, which gives businesses practical guidance for site planning and emergency preparation.

    Although the region is still prone to earthquakes, the Office of Emergency Management continues to coordinate the training, planning, and management of major emergencies and natural or man-made disasters. The city also publishes earthquake preparedness information and evacuation tools to help businesses and residents prepare for emergencies.

    Irvine's reliable network, strategic location, and business policies continue to make the city an emerging market for colocation investments. Local facilities such as DataBank's downtown Irvine site offer multiple meet-me rooms, fiber entrances, and 12 onsite carriers, which supports the city's role as an Orange County interconnection point.

    Frequently Asked Questions

    Why Do Companies Purchase Retail Colocation Services?

    Retail colocation centers offer flexible, customizable solutions that allow companies to scale their IT infrastructure when needed. In addition, colocation facilities are usually more cost-effective than building and maintaining an in-house data center. 

    This is because the facilities can spread the cost of data center infrastructure across multiple customers, reducing the overall cost per customer. 

    How Are Colocation Services Priced?

    The pricing of colocation services varies significantly depending on the customer's specific needs. However, some key factors can affect the prices of colocation services in California and other regions:

    • Space: Colocation providers charge customers for their IT equipment's physical space within the data center. The price range is typically measured in racks or rack units (RU). The cost per RU can vary depending on the location and the provider.
    • Power: Data centers charge customers for the energy their IT equipment consumes. Power consumption rates are typically measured on fixed kilowatts per hour (kW/h) or an agreed flat fee.
    • Bandwidth: Customers often pay for the internet bandwidth consumed. Data consumption can be measured in Mbps or Gbps. A provider might include some bandwidth, like 100 Mbps, at no additional charge.
    • Services: Some colocation providers offer additional services, such as managed services, remote hands, and equipment installation. Data centers charge each service separately, or customers pay a flat fee for a specific period. 
    What is a data center?

    A data center is a facility that houses computing, storage, and network equipment used to process, store, and deliver data.

    What is colocation?

    Colocation is renting space in a third-party data center for your servers and network gear while the provider supplies the facility environment such as power and cooling.

    How many data centers are in California?

    A statewide directory listing shows 289 data centers in California across 33 markets.

    Which California metros have the most data centers?

    Major concentrations include Santa Clara (75), Los Angeles (72), and San Jose (55), with additional clusters such as Sacramento (22), San Francisco (16), Irvine (15), and San Diego (14).

    Why is California a major colocation market?

    California supports large technology and media ecosystems and has dense carrier connectivity in key metros, which drives demand for interconnection-heavy sites and regional deployments.

    How do I choose between Los Angeles, Silicon Valley, and San Diego for colocation?

    Match the metro to latency targets and partner connectivity needs, then validate carrier availability in the exact building and test performance before committing to long terms.

    What should I ask about earthquake readiness at a California colocation site?

    Ask what seismic standards apply to the building, what power and cooling failure scenarios are tested, and what documentation exists for structural and resilience work.

    What usually drives the monthly price of colocation in California?

    Common cost drivers include committed power, cabinet or cage size, cross-connect count, bandwidth commit, remote-hands usage, and contract length.

    Can I run colocation in California without visiting the facility often?

    Yes, remote hands allows on-site technicians to perform approved physical tasks when your team is not local.

    What paperwork should I expect to get connectivity turned up in a colocation facility?

    Cross-connects often require facility ordering steps and provider paperwork, and some connectivity setups use documents such as LOA-CFA depending on the service and carrier path.
