Equinix vs Digital Realty for Colocation Buyers

The two biggest names in data centers, and the cleanest version of the choice underneath every colocation decision: adjacency or scale. Equinix owns the buildings where carriers, clouds, and exchanges physically meet, and sells the privilege of being in the room. Digital Realty runs one of the largest data center platforms in the world and sells room to grow, from a single cabinet to a private suite, in nearly any metro a business will ever need.

Choose Equinix when

• The requirement is adjacency: private cross connects to your cloud, your carriers, or your counterparties
• Latency and exchange proximity are the point, as in trading, media, and network businesses
• You need the same interconnection ecosystem in many metros under one contract
• You will actually use the neighborhood you are paying to be in

Choose Digital Realty when

• The plan is growth: start with cabinets, expand to a cage, end in a suite without changing providers
• Dense AI class hardware is on the roadmap and power per rack drives the design
• You are consolidating scattered server rooms across several metros onto one platform
• The workload needs power and cooling at scale, not an exchange floor

The pricing reality

Equinix prices per cabinet with metered power on top and cross connects billed monthly each, at a premium over the market that reflects what the buildings are. Digital Realty prices per kilowatt or per cabinet by market and density, with real movement between metros on the same specification. Both are quote based everywhere, and both operate in a market where vacancy sits at record lows and renewals arrive with increases instead of concessions, so the first quote is rarely the best one on either side.

The verdict by use case: a business whose architecture depends on being where the networks and clouds meet should take Equinix and treat the cross connect fees as the product working. A business buying capacity, growth room, or a home for dense hardware should take Digital Realty and make the metros compete on the same specification. If you cannot name the cross connects you would order in the first quarter, you are probably a scale buyer paying an adjacency premium. We pull real numbers across every contender at once, free.
