Comparing the proprietary mainframe model to an open systems model shows
that:
Mainframe systems consist of monolithic components that can be
difficult to scale and limit flexibility.
The system uses proprietary technologies that were designed by the
same vendor.
These proprietary technologies can be relatively easy to manage
because the management tools do not have to contend with distributed,
open systems, but ease of management comes at the cost of scalability
and flexibility.
