Development of virtual testbed for study of
complex technical obects behavior re!uires application
of many various models" describing different phenomena#
$e have such state because in reality there are many
processes %hich are ta&ing place simultaneously# 'ome
of them are independent but some depends on each
other# 'o in general %e have oined different &inds of
some mathematical models# Real time simulation of all
processes %hich in influencing on final result of complex
obects behavior could not be organi(ed in one computer
because ade!uate modeling re!uires different &inds of
computer resources )for instance* high performance
calculation" data processing" visuali(ation" etc+# ,t the
same time different algorithms in frame%or&s of virtual
testbed re!uire different %ays of mapping on
multiprocessor architecture# Reali(ation of such
complexes re!uires large computational resources"
po%erful visuali(ation tools" and elaborated high-
performance numerical algorithms# Cloud computing is
the best %ay to solve the complex problems. -The cloud
computing is the computing in cloud %here as the cloud
refers to virtual servers/ distributed hosting" and shared
resources available over Internet# The users can access
the cloud for available service through the %eb bro%ser
and Internet connectivity# $e can also visuali(e the cloud
as a cluster of computers %hich are based upondistributed system that provide services in real time over
a net%or& and these characteristics ma&e the possibility
of using cloud computing# Figure. 1

No% days cloud computing is animportant and hot topic in arena of information
technology and computer system# 'everal
companies and educational institutes have beendeployed cloud infrastructures to overcome their
problems such as easy data access" soft%are
updates %ith minimal cost" large or unlimitedstorage" efficient cost factor" bac&up storage and
disaster recovery and several other benefits
compare %ith the traditional net%or&infrastructures# There %e study cloud computing
technology for marine environmental data and
processing# , cloud computing of marineenvironment information is proposed for the
integration and sharing of marine informationresources that its aim to perform empirical
re!uiring numerous interactions %ith %eb serversand transfers of very large archival data files
%ithout affecting operational information systeminfrastructure is highly desirable# In this paper" %e
consider about the cloud computing for virtual
testbed# That it related %ith real time infrastructureand the ta&e advantages of the cloud computing
technology#

cloud environment to minimi(e theimplementation cost and achieve more benefits
during communication# The cloud computing
platform is a most reliable and cost less solutionfor real time infrastructures" including
applications oriented to consumers"applications supporting the enterprise" and
applications for large scale sc ience# This trendis expected to continue for the foreseeable
future# 2o%ever" in many %ays research incloud computing is still immature# There is
limited understanding of basic issues" such
as exploiting data locality" load balancing"and identifying nodes and collections of
nodes that are damaging the overallperformance of an application# $e alsoexposed potential areas of cloud computing in
%hich interested researcher can contribute their
%or& to ma&e cloud computing more better incoming days#
The proposed concept of virtual testbeddefines process organi(ation as complicated
multilevel system consisting of the follo%ing
core components*
7 hierarchies of imitating models specifying
considered problem areas/
7 hierarchies of analytical models giving
simplified description of various parties of
modelled phenomena/
