Equinix is the largest vendor neutral, multi-tenant data center company. That may seem like a lot to unpack but it’s not that complicated of a business model. Equinix constructs buildings (land leased or bought) in key real estate locations for third parties (network service providers, enterprises and cloud providers, etc.) to house some of their data center hardware in server cabinets. Equinix provides the building, power, cooling, and connections to the Internet. Customers provider their own compute, storage and networking hardware. This customer relationship is called colocation and it’s the bulk of Equinix (and other data center companies’) revenues.
