As the last several years have shown, bigger is better when it comes to running a colocation data center services business. The biggest companies in retail and wholesale data center markets have further secured their dominance by acquiring hefty rivals, and there’s been a wave of consolidation in secondary markets, as smaller players seek to scale in order to compete.

Large multinational customers prefer a provider that can give them infrastructure at national or global scale, and if you’re a company with one or two regional locations, you’re mostly stuck competing with public cloud giants like Amazon and Microsoft for the dollars of local small and mid-size businesses.

he wholesale colocation data center market share of San Francisco-based Digital Realty Trust, the biggest company in that market, is about equal to the combined market share of the rest of the top-five providers in the category, according to data shared exclusively with Data Center Knowledge by Structure Research. Market share of Redwood City, California-based Equinix, the biggest player in the retail colocation market, is almost double that of the second-largest provider in the space: China Telecom.
