You can run a database just fine using provisioned IOPS EBS especially in a RAID 10 configuration. I'd like to see some data to the contrary as I've actually do

- cthalupa 12y agoThere's some disadvantages to using RAID 0 with EBS volumes in a performance dependent situation. Since you're writing to multiple EBS volumes for the RAID 1 portion of the RAID 10, you're going to require more EC2 to EBS bandwidth. EBS volumes are replicated across multiple servers, so you don't necessarily need the reliability, especially if you're replicating the data elsewhere. YMMV, of course, and everyone has different priorities and different levels of what constitutes acceptable risk, but RAID 0 with EBS isn't quite the data death wish it is with physical hardware. http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/raid-config.html http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/raid-conf...
- bkeroack 12y agoAs have I. I'm not saying it isn't possible, rather that the performance pales in comparison to (and is much more expensive than) real hardware.
