The queued components service enables you to create
components that can execute asynchronously or in
disconnected mode.

Queued components ensure availability of a system even when
one or more sub-systems are temporarily unavailable.
Consider a scenario where salespeople take their laptop
computers to the field and enter orders on the go.


Because they are in disconnected mode, these orders can be
queued up in a message queue. When salespeople connect back
to the network, the orders can be retrieved from the
message queue and processed by the order processing
components on the server.
