See how everyone define "Cloud Computing" in a different way... It's not just one thing, there are lots of different things that comes from different people but basically, we are using the same computers connected to the network providing services to customers. Cloud computing is something that can balance up and down instantly by using the shared resources (physical or virtual). VPS’s that are managed by Xen with a combination of NFS and iSCSI storage, LDAP+Kerberos, load balancer and a master SQL cluster is “cloud”. They are not loaded with the difficulties of how everything works, they are simply having an interface to manage their data and services. As the requirement/traffic increases more Xen nodes can be provided and assigned different tasks to ensure their specific applications run in the most effective and optimal way.
