Earlier this week, CRN reported that Apple (NASDAQ:AAPL) has now drastically cut its spending at Amazon.com's (NASDAQ:AMZN) all-important Amazon Web Services. Instead, the Mac maker is cozying up to Alphabet's (NASDAQ:GOOG)(NASDAQ:GOOGL) Google Compute Platform. Apple and Alphabet signed the deal late last year, and has started transitioning away from AWS.

It's about time.

She called it
The news comes shortly after Morgan Stanley analyst Katy Huberty predicted that Apple may want to "move away from AWS," based in part on comments from the January earnings call. Apple noted that a big part of its projected growth in capital expenditures for 2016 relates to expanding data center infrastructure. Apple plans on spending an incredible $15 billion in capital expenditures in fiscal 2016, up from $11.2 billion in fiscal 2015.

As Apple's customer base grows, so does its need for cloud infrastructure to facilitate the wide range of services that it offers. For reference, here is the quote that Huberty is referring to from CFO Luca Maestri (via Thomson Reuters StreetEvents):

Then we've got data centers. And data centers is a growing expenditure for us, because, as we mentioned in our prepared remarks, our installed base of customers ands devices is growing, and is growing very significantly. And the data center capacity that we put in place is to provide the services that are tied to the installed base. So that type of expenditure goes together with the installed base.

By Huberty's estimates, Apple would be spending a little over $1 billion on AWS in 2016, or 9% of what she her estimates for total AWS revenue for the year. Total AWS revenue last year was $7.9 billion. Either way, losing a big chunk of Apple's business will be a big blow to Amazon. But AWS is growing so fast (up 70% last year) that it can likely make up for the loss, or at least mitigate its impact on its most profitable business.

Among Apple's competitors, the company's rivalry with Amazon is perhaps the most bitter. Both companies continue to spurn each other's services as much as possible, particularly in areas like online video streaming.

Sending it back where it came from
Apple is now expected to spend $400 million to $600 million on Google Compute, although AWS remains in the mix for the time being. It's not clear if this estimated spending range is an annual amount or to purchase a set amount of capacity. Alphabet has been trying to aggressive undercut AWS in an effort to win over market share, and it seems to be working. Google Compute's overall performance also offers compelling value, too. More broadly, a price war has broken out among the major cloud infrastructure vendors.

It's of little consequence for Apple to cut a check to its rival, though. The two companies formed an amicable coopetition long ago. Besides, Google paid Apple an estimated $1 billion for its default search spot in iOS Safari in 2014 alone, so that money's just going back where it came from anyway.
