 "Tests Show Non-Uniformity In Cloud-To-Cloud Data Transfer Speed")
Enterprise storage company, Nasuni has released the findings of its report ‘Bulk Data Migration in the Cloud’. In the report, Nasuni provides details and results from tests in which it moved data directly from one cloud to another using cloud compute resources.
The company’s engineers conducted tests on the top three cloud storage providers from its December State of Cloud Storage Providers report.
Nasuni typically uses Amazon S3 as the back-end cloud storage component for most of its customers, because Amazon S3 was, by far, the top performer in previous tests. As such, Nasuni wanted to see how long it would take to move a sizable storage volume from Amazon S3 to another Amazon S3 bucket, to Microsoft Windows Azure and to Rackspace.
While transmission speeds differed significantly depending on the time of day and the number of compute machines used to transfer the data, Nasuni’s tests enabled it to estimate the minimum amount of time it would take to migrate a 12 TB storage volume:
• Amazon S3 to another Amazon S3 bucket: Four hours
• Amazon S3 to Microsoft Windows Azure: 40 hours
• Amazon S3 to Rackspace: Just under one week
• Microsoft Windows Azure to Amazon S3: Four hours
• Rackspace to Amazon S3: Five hours
The biggest limiting factor appears to be the cloud’s write capability, as all transfers to Amazon S3 were between four to five hours, whereas writing to Microsoft Windows Azure and Rackspace was at least an order of magnitude longer.
“Enterprise IT professionals increasingly want to know that any data they store in the cloud is not ‘stuck’ in that cloud,” said Andres Rodriguez, CEO of Nasuni. “Vendor lock-in is a real fear and no one wants to be confined to one cloud any more than they would want to be limited to one disk drive or one storage array. Enterprises must maintain flexibility and these tests demonstrate that, while data can be moved from cloud-to-cloud relatively quickly with some providers, others require an unacceptable amount of time to complete,” he added.
