Overview

Remote service is the way to execute logic on different application. Currently JSON encoded, HTTP based transport is supported. In future there is a plan for more generic RPC support.

Usage:

# Configure the remote endpoint.
Rddd.configure do |config|
  config.remote_services = [
    {:namespace => 'projects', :endpoint => 'http://products.dev/'}
  ]
end

# Execute service
class Test < Sinatra:Base
  get '/:account_id/projects' do
    execute_service(:projects__list, params[:account_id])
  end
end

# Finally here is the remote app
class Projects < Sinatra:Base
  post ':service_name' do
    execute_service(params[:service_name], request.body)
  end
end

As you can see remote app uses the service bus as well. This architecture would allow you pull part of your application to separate box without need for any change in your client or services code base.
