Hybrid Cloud Computing: Businesses will Ultimately Blend the Best of Private and Public Clouds
“In the past three years, private cloud computing has moved from an aspiration to a tentative reality for nearly half of large enterprises. Hybrid cloud computing is at the same place today that private cloud was three years ago; as actual deployments are low, but aspirations are high,” notes Gartner in a recent press release.
While half of large enterprises already have already set up private cloud services, there are few examples of hybrid cloud solutions. Despite that, Gartner sees hybrid cloud services as the best way for businesses to balance parameters like cost, performance and security, and they expect that nearly three-quarters of large enterprises will have hybrid cloud deployments by 2015.
Building a hybrid cloud isn’t easy. There are both technology and cultural challenges that businesses need to overcome. Thomas Bittman, vice president and distinguished analyst at Gartner, said that private cloud technologies are “relatively immature and evolving.” And he notes that “an ingrained IT culture focused on technical expertise doesn’t fit a fully automated, self-service model that requires a service-oriented, team approach.”
Cloud computing provides very attractive benefits to businesses. Bittman said that “virtualization reduces capital expenses, and standards and automation reduce operational expenses.” But he warns that “too often, private cloud projects are started by choosing a technology, but technology itself does not solve the transformational people and process issues. It is much better to focus first on an approach to make transformative changes. In many cases, that means creating a separate organisation outside of traditional IT processes — at least to incubate these projects — and focusing first on a simple project that has buy-in between IT and IT’s customers.”
