This is identical to solutions that use tmpfs on linux for
database storage or dealing with a fully failed storage
system. Think about what you'd do if a RAID controller
fried and botchd your entire array at once. You'll feel
just the same way if a box using ephemeral storage goes
down.
Your application needs to handle restarting transactions
and either a reverse proxy/load-balancer or client-side
switchover.
Depending on your tolerance for data loss you might need
three servers up, on as a secondary failover if the primary
fails so that you (pretty much) always have two servers up
to maintain the data. The last server only has to last long
enough for a restart and recovery so it might not have to
be very heavy duty, it's main purpose is to keep the database
alive long enough to recover the "real" server.
Q: Why not just use RDS?
It'll be simpler.
