configure, develop, maintain and install every application to work and use
for their purpose that also requires a strong maintenance team to maintain
them and service them on a daily basis, one can easily just use and pay for
that price that they require for their usage. That is why for proper and best
utilization, one can pay only for their usage of their applications.
