ClearSky Data announced recently that it had launched a global storage network designed to simplify storage infrastructure and free IT departments from the usual hassles of backups and disaster recovery. Although the cloud was designed to address these issues, ClearSky argues that cloud technology alone falls short of giving businesses the performance they need.
One of the differences in ClearSky’s global data network from other services is that it categorizes a customer’s data as ‘hot’, ‘warm’, or ‘cold’ and uses a caching scheme that optimizes performance. The ‘hotter’ the data is, or more frequently it is accessed, the closer it physically resides to the customer. Hot data resides in a cache close to customer applications; warm data resides in a data center within 120 miles of the customer, and all data is kept at multiple locations, but would take longer to access.
This addresses latency problems that ClearSky says the typical cloud service has. With these providers, data is usually not optimized as it is with the hot-warm-cold caching scheme, forcing the customer to wait longer for data to arrive. Not only is there latency, but the wait times are often unpredictable, adding further to the frustration.
