Nasuni Corp. released results from its third biennial State of Cloud Storage Report, which tested the write/read/delete speeds, availability and scalability of the top three public cloud storage providers.
Microsoft Azure's Blob Storage came out on top overall, with Amazon S3 a very close second, though it did beat out Azure in some important aspects. Google Cloud Storage lagged far behind the top two.
Microsoft has made enormous strides with its cloud storage service since Nasuni issued its first cloud storage provider (CSP) report in December 2011. In that report, though Microsoft performed well, Amazon was clearly superior. That changed in the February 2013 CSP report when Microsoft took the top spot over Amazon. The 2015 CSP report shows that Microsoft has managed to hold on to its position as the top cloud storage performer.
Nasuni publishes this biennial report to share the information that it gathers in order to properly evaluate CSPs for its own use. In much the same way that traditional enterprise storage vendors use commodity disk drives as components in their products, Nasuni uses public cloud storage from the major CSPs as a component in their cloud NAS service. And just as these traditional storage vendors constantly test commodity disk drives, Nasuni also regularly tests the major public storage clouds. The company must monitor every change, improvement and update within the CSP market to know which CSPs best enable it to provide the highest quality service and deliver on its stringent SLA.
This year, Nasuni narrowed its test to just three providers: Microsoft Azure's Blob Storage, Amazon Simple Storage Service (S3) and Google Cloud Storage. Originally, Nasuni had also planned to test HP's Cloud Object Storage and IBM's SoftLayer; in fact, these two providers were tested in a limited capacity. However, HP made a significant strategic change to their service, leaving Nasuni unsure of how the service would evolve over the coming year, and Nasuni's experience with IBM was checkered with scheduled outages that made testing very problematic.
In addition, in Gartner's most recent Magic Quadrant for Public Cloud Storage Services (Gartner, 9 July 2014), Microsoft Azure and Amazon S3 are the only Leaders, while Google is the only Challenger, further justifying that the tests be restricted to these three CSPs. (+)
