Tech giant Apple, has signed a deal with Google to use the company’s cloud computing platform for iCloud and other undisclosed Apple services.

The deal which is is rumored to be worth between $400-$600 million has seen Apple switch from Amazon.

This means Apple will be relying on one of its rivals for certain services, though this may not be long since Apple is building three brand new data centers located in Arizona, Denmark, and Ireland.

When it comes to the cloud, one company buys and operates huge amounts of compute power, storage and networking bandwidth that it rents out to businesses that do not want to build more of their own infrastructure.
