IBM,
the global computing giant, has said it is investing more than $1.2bn
(£735m) expanding its data centres and cloud storage business.
It plans to build 15 new centres around the world, bringing the total number up to 40 during 2014.IBM bought cloud services company SoftLayer for $2bn last year, and this investment will double the subsidiary's storage capacity, the company said.
IBM believes the cloud services market could be worth $200bn by 2020.
Businesses are increasingly leasing data storage, computing power and web hosting services from a growing number of specialist cloud companies - effectively outsourcing their IT needs to cut costs and improve efficiency.
IBM says it has added 2,400 new clients since it acquired Dallas-based SoftLayer.
