Online retailer Amazon is reportedly planning to set up data centres in all major countries as part of efforts to make its cloud computing division, Amazon Web Services (AWS), the major part of its business.

Despite investors’ concerns over high spending and sacrificing margins, AWS chief Andy Jassy intends to continue investments in the unit.

Jassy told Reuters: "We are prepared to invest as much as it takes to grow the business."

Earlier, Amazon said in its filings with the US government that it will put in $1.1bn over the next three years to set up a new data centre in central Ohio.This will be in return for tax breaks.

The tech firm also launched a Cloud Drive API that enables third-party application developers to integrate Cloud Drive into their apps, providing users with additional functionality and new features.

Amazon said in a statement: "Now millions of Amazon customers can edit their Cloud Drive photos and documents, print photos, organize cloud services, and more with the third-party app integrations launched today.

"For developers, Cloud Drive eliminates the worry about the complexities of storage, conversion for multiple devices and screen resolutions, metadata management, indexing, search, and sync functionality."
