The global market for the 'transformational' cloud computing technology is expected to be worth over USD 30 billion (around Rs 1.35 lakh crore) in the next four years, according to a senior official at research group Gartner.

Cloud computing refers to the technology, whereby entities can share resources and software on-demand through the internet.

"It (cloud computing) is an extremely attractive technology for entities. The worldwide market for this technology is expected to be over USD 30 billion by 2014," Gartner Vice-President (Research) Milind Govekar told PTI.

Noting that developing markets such as India have an edge in adapting to cloud computing, he said that service delivery (using this technology) would be crucial.

"Companies need to embrace many changes with cloud computing and services would go through huge transformations with this technology," he added.

Govekar noted that cloud computing would be more environment friendly and efficient than many traditional technologies.

In a recent research report, he cautioned that while using cloud computing, enterprises must curb their old habits of over provisioning infrastructure.

"(This) would result in diminished resource efficiency and environmental benefits, particularly for private cloud environments," he said.
