Cloud Computing
Cloud computing has recently emerged as one of the buzzwords in the ICT
industry. Numerous IT vendors are promising to offer computation, storage,
and application hosting services and to provide coverage in several continents,
offering service-level agreements (SLA)-backed performance and uptime promises
for their services. While these “clouds” are the natural evolution of
traditional data centers, they are distinguished by exposing resources (computation,
data/storage, and applications) as standards-based Web services and
following a “utility” pricing model where customers are charged based on their
utilization of computational resources, storage, and transfer of data. They offer
subscription-based access to infrastructure, platforms, and applications that
are popularly referred to as IaaS (Infrastructure as a Service), PaaS (Platform
as a Service), and SaaS (Software as a Service).
