The development of high speed Internet access,
Web 2.0 applications and Virtualization techniques have
made Cloud computing a leading edge technology. A user in
‘Cloud’ runs web based application over Internet via
browser with a look and feel of desktop program. Cloud
computing provides dynamically scalable and virtualized
resources as a service over the network at a nominal initial
investment. Data-center works as backbone in Cloud
computing where a large number of servers are networked
to host computing & storage needs of the users. The area
which needs more attention is Latency Optimization for
cloud architecture to work as ubiquitous as expected. Many
data intensive applications produce enormous amounts of
data which travel on cloud network. As the cloud users grow,
cloud architecture should accommodate movement of
voluminous data to avoid data congestion in the network. In
this paper, an intelligent & energy efficient Cloud
computing architecture is proposed based on distributed
data-centers to support application and data access from
local data-center with minimum latencies. It was found that
the proposed architecture is efficient for business
entrepreneurs, suitable to apply for e-Governance and
provides a green eco-friendly environment for Cloud
computing
