Question 9: A Fortune 100 company is migrating its Enterprise Application Integration (EAI)
architecture to SOA.
The intent is to begin exposing its capabilities to business partners. The CIO is thinking about
building a
high speed, custom messaging solution so there is capacity for future growth.
What should the SOA Designer say about the long-term implications of that direction?
A. A custom messaging solution could provide performance advantages if development
priority is
allocated to provide standards-based connectors and adapters for business partners to
connect.
B. XML messages can be transformed at wire speed using Enterprise Service Bus (ESB)
appliances like
WebSphere DataPower SOA Appliance, so it is not necessary to be concerned with that part
of the
system's performance.
C. Total cost of ownership will increase with custom middleware. Open standards-based
commercial
messaging products are more interoperable, extensible, scalable, replaceable, and reliable
than
custom-built systems.
D. It will take a serious commitment to detailed technical support to make this happen. It is
always a
tradeoff between standards-based compliance and performance. The implementation of the
custom
messaging will need to provide serious performance advantages to business partners.
