In his recent article Mark Olson, a Senior Principal Engineer at AWS, recounts how Elastic Block Store (EBS), cloud-based block storage, transformed from a simple service using shared hard disk drives (HDDs) into a massive distributed storage system capable of handling over 140 trillion operations daily.
