Mix and Match Cloud and On-site Systems
More companies than ever before are blending cloud and on-premises storage, says Dick Csaplar, an analyst at Aberdeen Group. On-premises systems are "fast, immediate, close by," he notes, adding that they have "very little latency because you're not dealing with a WAN -- just a LAN."
But as the data ages -- and in some cases, before it's even archived -- "you can relocate it in the cloud and take advantage of the low cost of cloud storage, but still have direct access to the data" even if there's a delayed response, says Csaplar. Red Hat did this with its hybrid cloud storage architecture after acquiring Gluster, an open-source storage software company, in October 2011. Swedish vendor CompuVerde has a similar offering.
"They all have different variations on the theme of what [storage] is on-premises versus what's in the cloud," Csaplar adds. "But this link of making your storage continuous across both the cloud and on-premises is a trend I think we're going to see a lot more of as well."
