Cloud is a marketing term and is pretty worthless. Most of the time cloud = some datacenter, datacenter usually = rented space in someone else's datacenter or a VM. Cloud does not automatically mean better, faster, safer. You can build an app to be more resilient but you dont get that for free just because there's cloud in the title.

The author seems to think there's a magic cloud switch that makes your app work in multiple datacenters all at once. Apparently virtualisation makes that easy. VMs are going to keep you data in sync? They're going to fail over perfectly in all conditions? They're going to make sure data is routed to the best zone?
