One of my small python web app hosts on GAE
but I prefer to change its database to couchbase.
GAE database is too special which rely on GAE and not good for future migration.
Can python app on GAE(google app engine) access Couchbase server cluster host on VPS/dedicated server?
(of course they are not in same local network with GAE)
if sure, what need to care(firewall, port policy and all others) for Couchbase server being open to web, ?
