Equinix is a retail provider of data centers, enabling hundreds of enterprise tenants to house their servers and networking equipment in a colocated environment. Tenants can then connect with each other, cloud service providers, and telecom networks. Equinix operates over 200 data centers in about 50 markets worldwide and owns just less than half of them. The firm has nearly 10,000 customers, including 1,700 networks, that are dispersed over five verticals: Cloud and IT Services, Content Providers, Network and Mobile Services, Financial Services, and Enterprise. More than 80% of Equinix's revenue comes from renting space to tenants and related services, and more than 15% comes from connecting customers with each other. Equinix operates as a real estate investment trust.
