Remote Object Activation is a concept in distributed
computing that is used to increase performance. It enables the
developer to specify which services
should be "activated" or loaded into memory when the service engine
is booted. It may be desirable to activate some services on-demand.
Although this will increase the amount of time that it takes to
run the operation the first time that it is called, after the
first invocation, performance associated with operation execution
should become inline with preloaded services.

The benefit of on-demand loading is to not pre-allocate
resources that may never be utilized (memory, disk, etc.), thus
allowing more resources for those services that are commonly used.
Remote Object Activation was considered out of
scope in the SOAP specification. Although,
SOAP Server vendors may choose
proprietary means to implement this functionality. Remote Object
Activation is a service design
issue.
