I'm considering similar issues right now. The problem with ephemeral storage is I don't know an easy way to back it up, while on an EBS it's a simple snapshot API call.
Otherwise, I believe the performance of the ephemeral (certainly in the case of large or greater, where you can RAID0 multiple disks) is way better than EBS. will On Wed, Mar 9, 2011 at 10:27 AM, Sasha Dolgy <sdo...@gmail.com> wrote: > Hi Everyone, > > Now that I'm past the problems of IP addresses changing ...
