NATICK, Mass., Feb. 19, 2013 /PRNewswire/ --Nasuni^®, a provider of
enterprise storage to large, distributed organizations, today released results
from its second annual State of Cloud Storage Report, which tested the speed,
availability and scalability of the top five public cloud storage providers.
In a reversal this year, Microsoft Windows Azure Blob Storage outperformed
last year's leader, Amazon S3.

Nasuni publishes this annual 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 Storage Infrastructure as a Service.

And just as these traditional storage vendors constantly test commodity disk
drives, Nasuni also regularly tests the major public storage clouds. Nasuni
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 100 percent reliability SLA.

In last year's report, tests demonstrated that Amazon S3 was the top performer
due to its overall performance and consistent results. Although other
offerings showed potential, they had not yet reached the level of performance
that Amazon S3 demonstrated. 

For the 2013 CSP Performance Test, Nasuni measured performance across three

  oWrite/Read/Delete Speed: This test measures the raw ability of each CSP to
    handle thousands of writes, reads and deletes (W/R/D) with files of
    varying sizes and levels of concurrency.
  oAvailability: This test measures each CSP's response time to a single
    W/R/D process at 60-second intervals over a 30-day period.
  oScalability: This test measures each CSP's performance consistency (or
    lack thereof) as the number of objects under management increases into the
    hundreds of millions.

In 2013, Nasuni tested five clouds: Amazon S3, Microsoft Windows Azure Blob
Storage, Google Cloud Storage, HP Cloud Object Storage, and Rackspace Cloud
Files. While many cloud storage platforms are publicly available, only these
five platforms currently offer the combination of functionality, market
experience and price that Nasuni requires to support production customers.

Nasuni's engineers conducted all tests between November 2012 and January 2013
using virtual machines across most of the major cloud-compute platforms. Each
CSP was tested by using three "outside" machines (for example, Amazon EC2 was
not used to test Amazon S3) spread throughout the eastern region of the United

The results are clear: Microsoft Azure has taken a significant step ahead of
Amazon S3 in almost every category tested. Across the three tests, Azure
emerged as a top performer in all categories, and the leader in two out of

  oSpeed: Azure was 56 percent faster than the No. 2 Amazon S3 in write
    speed, and 39 percent faster at reading files than the No. 2 HP Cloud
    Object Storage in read speed.
  oAvailability: Azure's average response time was 25 percent faster than
    Amazon S3, which had the second fastest average time.
  oScalability: Amazon S3 varied only 0.6 percent from its average the
    scaling tests, with Microsoft Windows Azure varying 1.9 percent (both very
    acceptable levels of variance). The two OpenStack-based clouds – HP and
    Rackspace – showed significant variance of 23.5 percent and 26.1 percent,
    respectively, with performance becoming more and more unpredictable as
    object counts increased.

Overall, however, the test results demonstrated clear advancements on all
platforms over last year, including improved performance and fewer errors. It
is clear that the minimum bar is moving upward, which is good news for anyone
consuming or considering cloud storage. As more CSPs mature into
enterprise-class cloud storage offerings, organizations and vendors will be
able to leverage competitive advancements in price and technology to improve
their overall storage infrastructure.

"Microsoft's investment in its second generation cloud storage, which it made
available to customers last year, has clearly paid off," said Andres
Rodriguez, CEO of Nasuni. "With Amazon S3 and Microsoft Windows Azure, the
cloud storage industry clearly has two strong players to choose from. Even
more encouraging, however, was the marked performance improvement across the
board. As CSPs continue to mature, competition among top quality providers can
only benefit enterprise IT."
