1. Virtualization - Sharing of servers and storage devices and applications can be
migrated from one server to another with the help of this technique.
Virtualization is main enabling technology for cloud computing. Virtualization is an
abstraction of the environment which is dynamically made available to users and
here by many virtual machines run on a single physical machine.
What are the main purpose and benefits?
(a) With the help of this technique, the organisations which are dependent on
infrastructure are enabled to be infrastructure-less.
(b)Instead of putting data on servers or own desktop PC, customers can put data and
applications on cloud and use server within the cloud to do the processing.
(c) Running OS where hardware is not available.
2. Service Oriented Architecture(SOA)- In a similar manner like SOA, all
resources are given in form of services.
3. Utility Computing- Resources such as computing processing power as well as
storage is given as subscription or pay-per-use basis.
