NEW DELHI: Security software provider Trend Micro said the adoption of cloud computing services in India would largely depend on factors such as data safety.

"A major concern today about cloud services is the security of the data hosted on someone else's data centre in some part of the world, all the more when they are using the public cloud model," Trend Micro Country Manager (India and SAARC) Amit Nath told reporters here.

"We think more companies will move to the cloud once they are satisfied that their data is safe on the cloud," he added.

Cloud computing refers to a business model where companies access applications and software over the Internet on pay-per-use basis, without the need to own them. Companies save huge costs of buying products and reduce IT budgets.

According to a study by consulting firm Zinnov, the domestic cloud computing market is expected to touch USD 1.08 billion by 2015, from USD 110 million in 2010. There are three types of cloud services -- public, private and hybrid.

While public cloud hosts applications and information of various companies on the same data centre, in the private cloud model, companies ask the service provider to manage their data centres individually to avoid any data leakage.

Hybrid model is one where the company can choose the host the non-core applications on a public cloud, but have the important ones on a private cloud.

Trend Micro offers Deep Security and SecureCloud solutions for the cloud services, apart from solutions for individual users, SMBs, enterprises and government.
