This is according to a report from cloud storage provider Nasuni, which ran a test to assess six CSPs - Amazon S3, Microsoft Azure Blob Storage, Google Cloud Storage, HP Cloud Object Storage, and Rackspace Cloud Files.
The report noted that Azure, which is still very young in terms of market presence, though is showing positive growth, Amazon, which is a strong player has the potential to outsmart every other player in the market.
Last year, CSPs delivered over an exabyte of data under contract. This heralds a new era for how storage is delivered and consumed. Amazon's S3 service crossed the 1-trillion-object mark, and all major CSPs dropped their prices multiple times.
The report also notes that overall, the CSPs tested this year demonstrated clear advancements over last year, including improved performance and fewer errors. It is clear that the minimum bar is moving upward, which is excellent news for the cloud storage market as a whole. As more CSPs mature into enterprise-class cloud storage providers, organizations and vendors will be able to leverage competitive advancements in price and technology to improve their overall storage infrastructure.
The report also notes that HP, which is a relative newcomer to the CSP market, shows strong performance in write and read tests, suggesting that improvements in stability could make it a strong player in future.
