Equinix, Digital Realty and NTT are market share leaders in the colocation market, according to Synergy Research. But the market arguably remains fragmented, globally.
The three now control nearly 28 percent of the worldwide market and all have grown their market share over the last four quarters, both organically and through acquisitions.
Equinix had a 13 percent share in the first quarter of 2018. Equinix had a 17 percent share of retail colocation, while Digital Realty had a 28 percent share of the wholesale (business to business colocation) segment.
Equinix sells more to enterprises who need private cloud computing facilities.
