IT company Zenith Infotech today launched its private cloud computing solution 'TigerCloud', mainly for mid-sized organisations in the country, and is targeting about 200 customers in the first year of operations.

The company also expects the Indian operations to contribute 10-15 per cent to its revenues in the next 2-3 years.

"TigerCloud will help both mid-sized as well as large organisations to build their own private clouds at costs lower than public clouds," Zenith Infotech Chief Executive Officer AkashSaraf told reporters here.

Zenith Infotech has invested over Rs 200 crore on R&D for its private cloud products, he added.

Cloud computing refers to a pay-per-use model of computing where applications and software are accessed over the Internet and not owned by users. It helps IT companies to save huge costs as they do not have to invest heavily in IT infrastructure.

The company said India's cloud computing market is expected to reach USD 4.5 billion by 2015 and further grow to USD 15 billion by 2020.

"We expect to have atleast 200 customers in the first year of operations. Globally, we have done 6,000 implementations in about past year-and-a-half. Although going forward our major revenues will come from outside India, we expect the country to contribute 10-15 per cent to our revenues in next two-three years," Saraf said.

TigerCloud is based on Intel Xeon E3 processor family.
