HP Utility Data Center
The Utility Data Center, or UDC, was a product of Hewlett Packard. It was arguably the first attempt to sell a private cloud. It featured a graphical interface that allowed the user to construct a server "farm," including servers, OS provisioning, networking, firewalls, load balancers, and storage.
The product began in 2002 as an intellectual property acquisition, from a small services vendor, Terraspring, that had used the product to manage their own data center.
Originally termed project slinky, it was largely based out of the Fort Collins campus, and spent the first few releases porting the original solution from a stack based upon Solaris, Cisco switches, and WebSphere, to one based on HP-UX, HP Procurve, and Bluestone's Application server. Then the team spent considerable effort improving reliability, improving security, and creating packaging, procedures and documentation to make the solution salable as a product.
HP was on its second beta release when Sun Microsystems acquired Terraspring entirely, forming the basis for the Sun N1 Grid Engine.
