  Software-as-a-Service (SaaS) is a form of cloud computing that relieves the
user from the concern of hardware, software installation and management. It is
an emerging business model that delivers software applications to the users
through Web-based technology. Software vendors have varying requirements and
SaaS applications most typically support such requirements. The various
applications used by unique customers in a single instance are known as
Multi-Tenancy. There would be a delay in service when the user sends the data
from multiple applications to multiple destinations and from multiple
applications to single destination due to the use of single CSB. This problem
can be overcome by using multiple CSB concepts and hence multiple senders can
efficiently send their data to multiple receivers at the same time. The
multiple clouds are monitored and managed by the SaaS-CSB portal. The idea of
SaaS-CSB Portal is to provide a single pane of glass for the user to consume
and govern any service from any cloud. Thus, SaaS-CSB application allows
companies to save their IT cost and valuable time.
