Rails in the Cloud
Rails and the Cloud were made for each other. Both allow a rapid response to changing business requirements within their own domain, application development and IT infrastructure respectively. Rails, especially when deployment driven from something like Capistrano, allows a developer to easily respond to scaling requirements by expanding horizontally, adding new database and application servers, more often than not without any code changes (although this isn’t always true, even when a developer thinks it is). Most cloud services make provisioning those additional resources as easy as a click or two (or an API call or two)
