Today, IO is the second-largest private data center company in the world. The company first revolutionized colocation services in 2007, layering optimized thermal efficiency onto traditional offerings. Shortly after, in 2011, the company invented a patented modular data center with intelligent management and control mechanisms to drive further efficiency and density.
