Network management models
In practice, it is rare for an enterprise to completely embrace the centralized model. Some
applications may not "bolt on" to a particular framework, for example. Also, sometimes an
enterprise writes a "homegrown" application to cover an outage with the management server. In
addition, the distributed model is useful for times when the central management tool is
unavailable.
This resulting hybrid management model that combines elements of centralized management
with distributed management tools is most appropriate for large enterprises, or enterprises with
complex networks. It is also appropriate for smaller enterprises that can justify the cost of the
tools and have in-house expertise to keep the system running.
