There were a number of benefits identified way back then: hardware abstraction allowing easier image management and OS upgrades; options for higher availability and faster recovery; even fail-over. Virtualization enabled silo consolidation and importantly enabled better management of user capacity on servers. However, there is a price. Reduced… Public Cloud Computing – Economics and Throats to Choke When it comes to public cloud computing services that old adage of "fast, cheap, or good - pick any two" certainly hold true.

Amazon failed because of simultaneous failure of its EBS in two Availability zones. If you were dependent on one of these (or mirrored across the two) you lost access to the filesystem from your Instances. It may be sensible to move to the use of the S3 mechanism (or some portable abstraction over it) for… Technically, the Amazon Cloud didn’t actually failAmazon's Service Level Agreement (SLA) is so narrowly-drawn that it could easily be argued that the recent Elastic Block Store (EBS) outage wasn't a failure of Amazon Web Services at all.
