HP is planning to unveil a new tool that will give companies access to computing services as on need basis over the Internet without requiring to spend on expensive servers.

The trial version of the proposed cloud offering will be available on 10 May which will allow customers to perform small computing jobs for a cost of few pennies per hour, the company said.

The public cloud service will be available for startups and large organisations that want to use HP’s data centres to perform computing tasks.

Apart from computing capacity, the service will also include software tools which will allow Web-based businesses and other companies to run programmes, and even relocate programmes from their own data centres to HP data centres.

HP expects that the new offering will help the company compete with Amazon and other companies that have used data centres for cloud computing, including IBM, Rackspace Hosting, Verizon Communications’ Terremark unit and AT&T.

Amazon had started its Amazon Web Services business in 2006.
