問題4
I have a service composition with three services. Service A retrieves a list of country codes
from a database and keeps this data in memory while interacting with Service B and
Service C.
However, because Service A is concurrently invoked many times, and because
each instance of Service A loads its own copy of the country code data into memory, the
demands on the overall infrastructure become too high and performance and reliability are
negatively affected. Which service-orientation principle can be applied to help solve this
problem? Select the correct answer.
