Country's second largest software exporter Infosys Technologies is betting big on cloud computing and has already appointed about 2,000 experts to work on the technology.

"About eight months ago, companies were sceptic about cloud, but now they are talking about how to get there and what applications to put into the cloud. There is tremendous opportunity and we expect about 60 per cent of workload to shift on cloud in next 5-7 years," Infosys Vice President and Global Head Cloud Vishnu Bhat said.

Infosys, which already has more than 100 engagements, has over 2,000 experts already working on the technology to foster a robust cloud environment, he added.

Cloud computing is Internet-based service and facilitates sharing of technological resources, software and digital information. It operates on a pay-per-use model, helping companies to cut costs as they don't have to invest heavily in infrastructure.

"We are investing significantly in building new services, tools and platforms on the cloud platform," said Infosys Vice President and Global Head Business Platform Samson David.

He added that companies are opting for cloud not only to save costs, but also to reduce time-to-market for various applications and products.

Infosys set up a dedicated unit for cloud about a year ago. Also, as part of its 3.0 strategy, Infosys announced that it would focus on cloud computing, sustainability and enterprise mobility as new verticals of growth.

Recently, Microsoft CEO Steve Ballmer has said cloud computing had the potential to generate over three lakh jobs in India over the next five years.
