Word of the Day – hyperscale computing

Posted by: Margaret Rouse

“In the hyperscale market they’re building their own systems and a single controller is good. It’s one less failure point. For these types of organizations, it costs more to send people out to change a drive than it does to just failover to another server.

Today’s WhatIs.com Word of the Day is hyperscale computing, a distributed computing environment in which the volume of data and the demand for certain types of workloads can increase exponentially, yet still be accommodated quickly in a cost-effective manner.
