Re: Cloud-integrated storage: Hidden costs, or hidden advantages?
When you are dealing with petabytes of data, there are definitely some great advantages of getting everything centralized in the cloud, but yes, the hidden costs could add up quite a bit when you think of replication and disaster recovery. For one, because critical data is now stored fully in the cloud as opposed to locally on one site, you could be hit with a huge downtime should you need to failover that much data to another location if the cloud storage goes down. I've seen a few organizations do a selective backup/replication to an onsite for these reasons. A bit of a step backwards, but it is just one of those things that folks need to keep in mind when leveraging a single point of cloud storage for such a huge amount of data.
