We know a lot of you have been waiting for this: You can now create AppHarbor applications in the EU! This new feature will make creating fast and responsive apps targeted at European end users a lot easier. EU applications will still run on Amazon's high performance infrastructure, only they'll be running out of the EU-West region (Dublin) instead of US-East, where all current applications are located.
We have spent a lot of time making sure the AppHarbor platform is modular and scalable and this paid dividends when time came to spin up our new EU location. New applications are created in either the US or EU and existing applications cannot be moved, but we're already thinking about how to turn this up another notch to make AppHarbor a zero-configuration, multi-region, geo-load-balanced application platform.
Add-ons in the the AppHarbor add-on catalog will work with EU-based applications. Some (such as SQL Server) will intelligently provision resources based on where your application is located. We're working with our other add-on providers so that latency-sensitive add-ons can be provisioned in locations close to the application that is going to consume the add-on. For add-ons that do not currently support the EU, a warning will be displayed when they're provisioned to an EU application.
We're incredibly excited about this feature and we can't to see all the great apps that will soon be running out of the new AppHarbor EU location.
