Storage Switzerland, 9/4/15
Briefing Note: ClearSky Comes Out of Stealth
For many organizations, the thought of letting someone else manage their storage infrastructure is appealing. The cost and time required to acquire, maintain, manage and migrate storage is overwhelming and these organizations are turning to the cloud for relief. While the cloud is alleviating backup and archive concerns, it has fallen short when it comes to primary storage. The issue facing a cloud based primary storage solution is latency. ClearSky has emerged from stealth with a unique approach to solving the latency problem.
Latency – The Straw That Breaks Cloud’s Back
The idea of using cloud storage to replace primary storage is not new; there are several vendors with solutions on the market, but they all have to deal with latency when dealing with public cloud storage providers. The typical solution is to put an appliance on-site to act as a cache to the cloud. Since the appliance is on-premises it does eliminate cloud latency, assuming that the data being requested is on the appliance, if not then the data has to be retrieved from the public cloud and latency is reintroduced. The latency can be significant enough that applications may crash or users will complain. To avoid an application crashing due to latency, administrators are forced to either buy appliances with enormous local capacity, lock a particular application’s data on the appliance, or most likely do both. The problem with these work arounds is that the organization is still managing a significant amount of on-site data.
