It's not about technology, it's about redundancy. If you have two data centers, and you consolidate them into one data center, you've just increased your exposure to risk by orders of magnitude.
- lotu 12y agoThis depends on what type of failover you have though. If you 1000 small data centers and you consolidate into 100 larger data centers this doesn't mean an order of magnitude increase in risk. As long as any data center can take over for any other data center you probably don't need more than a handful of data centers for redundancy (you might want them for other reasons though).
- bcohen5055 12y agoWhat you described is not redundancy. In your situation if 1 of the 2 data centers went down you would still have a blackout somewhere. In a truly redundant setup the load would be shifted to the redundant center with minimal interruption to the customer (airspace).
