Have a monsterous DB setup
Cache the shit out of everything
Making the servers more lightweight
Scaling Rails

Reducing Server-side Complexity
Smaller requests
Ajax and JSON (very cachable!)
More requests, we want real-time
UI logic on the client

Less Web, More App
Sunday, April 1, 12
Sever-side becomes a true “App” Interface (aka API)
UI flow belongs to the client
Data over Documents
Sunday, April 1, 12
More JSON
Routing on the Client
Templates move to the Client too
Static pages matter less
Sunday, April 1, 12
Separation between API/platform and UI/client becomes more vivid.
Developing apps in a team becomes easier.
Automated testing becomes a lot more managable, less client-server integration tests.
Increased mashupability
Node is perfect for this new “data hub” role of the server-side
