computing provision. They are so much behind this latest paradigm that the
success is virtually guaranteed. The essential characteristics of cloud envi-
ronment include the following:
• On-demand self-service that enables users to consume computing
capabilities (e.g., applications, server time and network storage) as
and when required.
•
Broad network access
: Capabilities are available over the network and
accessed through standard mechanisms that promote use by hetero-
geneous thin or thick client platforms (e.g., mobile phones, tablets,
laptops, and workstations).
