Design a server topology in
which customers receive quality of
service (QoS) that reflects their customer status.
About this task
WS-Notification enables partitioned
topologies in which some servers
provide a different quality of service that can be used by customers
of
varying status. This might include configuring a cluster of servers
for use
by a particular customer in order to provide enhanced high availability
or
improved response times.
Procedure
- Get a statement of the qualities of service required by each
of
the applications and customers that use WS-Notification.
- Identify, from the statements you collected in the previous
step,
the distinct groups of QoS requirements.
- Specify
that higher QoS groups be isolated onto separate servers,
and that a separate WS-Notification service must be defined on these
servers
that can only be accessed by the required applications.
- Design a configuration such that service integration bus
topic
spaces used by the different brokers do not overlap in cases where
applications
with one QoS should be isolated from others.
