The new cloud centres will be in Washington DC, Mexico City, Dallas, China, Hong Kong, London, Japan, India and Canada, with plans to expand in the Middle East and Africa in 2015.
IBM said the investment will bring up its data centre count to 40 this year and double cloud capacity for SoftLayer, which leases online storage space to companies and was acquired by IBM last year for $2 billion.
This global expansion is aimed at accelerating into new markets based on growing client demand for high-value cloud, the company said in a statement.
IBM said the global cloud market is estimated to grow to $200 billion by 2020.
More companies are opting for cloud computing, which lets them rent computing power, storage and other services from data centres shared with other customers, which is typically cheaper and more flexible than maintaining their own.
IBM also said it will use web hosting technology from SoftLayer for the delivery of its cloud services. IBM said since its acquisition of Dallas-based SoftLayer, the business has added 2,400 new clients.
