That S3 outage sure concentrated people’s minds. And almost simultaneously, EMC announces that they’re getting into cloud storage. It’s obvious to me that we’re nowhere near having worked out the economics and safety and performance issues around where to put your data. There are some areas of clarity; geek über-photog James Duncan Davidson, in The Economics of Online Backup, shows that for a person with a ton of personal data, the online option is really unattractive. And you do hear sotto voce rumbles about going online in the geek hallways, for example “Amazon web services: 3x the price, 0.5x the reliability, and lower scalability than DYI. Buy only for the low capex and lead time.” That’s from Stanislav Shalunov, who by the way is a damn fine Twitterer. The big questions remain open.
