Organizations across the Globe are adopting Cloud at a staggering rate, consuming various flavors of cloud such as Software-as-a-Service (SaaS) ,Platform-as-a-Service( PaaS ) & Infrastructure-as-a-service (IaaS). As a result, traditional and new breed of applications are moving from in-house hosted datacenters to cloud.
