We're using Cassandra on AWS at SimpleGeo. We software RAID 0 stripe the ephemeral drives to achieve better I/O and have machines in multiple Availability Zones with a custom EndPointSnitch that replicates the data between AZs for high availability (to be open-sourced/contributed at some point).
Using XFS as described here http://developer.amazonwebservices.com/connect/entry.jspa?externalID=1663 also makes it very easy to snapshot your cluster to S3. We've had no real problems with EC2 and Cassandra, it's been great. -Ben Standefer On Thu, Jun 3, 2010 at 11:51 AM, Eric Evans <eev...@rackspace.com> wrote: > On Thu, 2010-06-03 at 11:29 +0300, David Boxenhorn wrote: >> We want to try out Cassandra in the cloud.
