Equinix

Equinix is the world's largest data-center and interconnection company, operating a global network of colocation facilities where clouds, networks, and enterprises interconnect. As AI drives demand for dense compute and high-bandwidth interconnection, Equinix provides the neutral physical venues — and increasingly liquid-cooled, high-power capacity — that AI infrastructure depends on.

Founded in 1998, Equinix built its business on carrier-neutral colocation and the network effect of its Internet Business Exchange (IBX) data centers, where thousands of networks and clouds physically interconnect. It operates as a real estate investment trust with facilities across dozens of metros worldwide.

The AI era is reshaping its offering: training clusters need far higher power density and liquid cooling than traditional colocation, and Equinix has invested in retrofitting and building capacity to support GPU deployments, along with private-interconnection products that link enterprises to AI clouds. Its xScale hyperscale facilities serve the largest cloud tenants.

Equinix's strategic value is interconnection: as AI workloads span multiple clouds and on-premises systems, its dense fabric of cross-connects becomes more valuable. It competes and partners with Digital Realty and a growing field of AI-specialized data-center developers.
