DAAS.com is about buying infrastructure like water, gas or electricity: by the unit.
DAAS.com integrates servers, storage, networking in one single interface and customers will use 3 simple units (also called credits) to use capacity in the cloud:
See here an example implementation with the DAAS.com cloud:
Processing hours: 1Ghz, 512MB RAM, 4GB primary storage per hour
Archive Storage hours: 1GB per hour
Bandwidth in/out: 1GB transferred in/out the cloud
It will be these 3 simple units that customers can use to build their own datacenter:
It does not matter how customers want to use the units, they can spread out the capacity in time and decide themselves what infrastructure to bring live: many small servers or fewer large servers, all depeding on how much units they have left.
