In most of the private cloud implementation scenarios, the authors came across IAAS as the sole way of implementing cloud. In IAAS, the concept of very high scalability, reliability, availability and on demand provisioning is limited to hardware/virtual machines. Though implementing IAAS qualifies an organization to call itself as cloud enabled, there needs to be a PAAS that augments the clouds efficiency to maximize the bang for the buck. It would also propel the organization further up in the cloud maturity index.
