Nirvanix's Demise Emphasizes The Need For Hybrid Clouds And Storage Mobility

The untimely demise of Nirvanix has left over 1,000 customers scrambling to migrate data off of the cloud storage service provider and with a short two-week timeframe to save their data. While providers have gone to great lengths to make data import into the cloud easy by eliminating data ingest fees, large data sets in the cloud are difficult to retrieve or migrate to a new target. The recent example with Nirvanix highlights why customers should also consider exit and migration strategies as they formulate their cloud storage deployments.

One of the most significant challenges in cloud storage is related to how difficult it is to move large amounts of data from a cloud. While bandwidth has increased significantly over the years, even over large network links it could take days or even weeks to retrieve terabytes or petabytes of data from a cloud. For example, on a 1 Gbps link, it would take close to 13 days to retrieve 150 TB of data from a cloud storage service over a WAN link.

To minimize risks in cloud storage deployments and facilitate a graceful exit strategy (just in case things go sour), I recommend customers take the following steps:
