Amazon and Google have done a remarkable job promoting public cloud, as VMware, Cisco and OpenStack have done similarly with private cloud. Yet last week at the Gartner Data Center Conference 2012 the dominant theme was neither public cloud nor private cloud, but rather hybrid cloud. The hybrid cloud is form of cloud computing whereby applications and services can run across multiple clouds, colocation and data centers seamlessly, as a single hybrid cloud.
Although it has been discussed for years (see this article from InformationWeek in 2010 on the now defunct infrastructure 2.0 working group), the technical and business barriers have kept it, until recently, confined to slides and drawings and tactical tools. See my recent high velocity cloud blog for more background.
This theme is very relevant to virtually all of today’s technology companies, including Cisco, HP, Oracle and others, because it represents a revolution in how apps and services are delivered. Hybrid cloud represents the ultimate decoupling of an application, OS and service from a specific piece of hardware or even location. Hybrid cloud will do to the tether between apps and services and clouds what VMware did to the once powerful bond between apps, operating systems and individual servers.
Hybrid cloud is a game-changer.
