Can't say anything for Heroku, but Engine Yard will have Sydney as an option very soon. > ie. would regional servers (eg. an australian, a european, an asian mongrel > instance etc.) even achieve time savings for server-side rails code if they > need to talk to a central once-off database (eg. in the USA)..

Having an app hosted in Sydney talking to a DB server in the USA will be much slower than having both servers in the USA - this is because your app will typically make multiple DB calls per request, so you're multiplying the delay rather than reducing it. That said, with smart caching and local DB read slave[s] a read-heavy app might work out with this approach. Your writes back to a central DB will still be slow, and your local read slave will be much more susceptible to replication lag - however for some apps this isn't much of a problem. It really depends on the app, and is something you'd have to test! -- http://johndalton.info http://www.linkedin.com/in/johnrdalton -- You received this message because you are subscribed to the Google Groups "Ruby or Rails Oceania" group.
