If you are a hyperscale (Cloud) data center manager, one of your top concerns is how to get the maximum amount of computing work done per Watt of power consumed. With that in concern at the forefront Cloud Providers like Google, Microsoft, and Facebook have strong incentives to explore new solutions for delivering compute cycles. Rumors coming out of Facebook suggest that it is looking to move away from its current X86 architecture platform in favor of servers based on ARM Holdings Cortex processor range. Porting an entire service to a new processor platform may not appear to be a sensible direction to take but porting to a new architecture is more a financial consideration than a technical one. If the cost per unit of performance justifies it , it is cheaper to pay a few programmers to rework the apps for a new architecture than it is to buy more servers.
