Amazon’s S3 Simple Storage Service has outperformed Microsoft’s Windows Azure Storage and all other major providers in an extensive study testing the feasibility of businesses using cloud services for primary storage, data protection, and disaster recovery.
Nasuni, which sells data protection services that work across any type of cloud storage, says it has been testing the 16 largest cloud storage providers (CSPs) since April 2009 to determine the best services for its customers. Ultimately, only six of the 16 providers passed Nasuni’s testing—in addition to Amazon and Microsoft, the other winners were Nirvanix, Rackspace, AT&T Synaptic, and Peer1 Hosting. Both AT&T and Peer1 use EMC’s Atmos platform on the back end, although EMC itself discontinued its own public cloud based on Atmos.
While these six are, apparently, ready for real-world use, Nasuni politely declined to say which ten services failed its test, so we can’t warn you away from those vendors. But Nasuni does say the difference between the ones who passed the tests and those that didn’t is in some cases quite large. When Nasuni tested the providers for scalability by continuously writing small files of 1KB for weeks on end to determine error rates and performance, two of the eight providers that made it through this stage of testing failed, and others couldn’t complete the test.
“Without proper testing, it is impossible to differentiate between an industrial-strength CSP and a lesser operation,” Nasuni said. “In fact, some providers have asked Nasuni to cease testing at this stage because they said it was negatively impacting their customers, which is a truly frightening statement. True cloud storage should be able to accommodate billions of files without any visible strain. Those CSPs that faced performance issues under Nasuni’s test are simply not equipped to deliver an appropriate level of service to customers.”
