IDC Innovators are emerging vendors with revenue under $100 million that have demonstrated either a groundbreaking business model or an innovative new technology or both. This IDC Innovators study covers vendors with innovative composable/software-defined infrastructure technologies that improve the efficiency of computing (servers) and data persistence (storage) hardware utilization in the datacenter. Businesses that employ technologies from the vendors discussed in this document (see Figures 1–4) can seek to extend the return on their infrastructure investments. They can seek to achieve significant cost savings through adopting new but inexpensive combinations of commodity hardware and innovative software. Vendors covered in this study are TidalScale, DriveScale, and Cloudistics.
