Arcitura Education S90.09 Exam - Topic 4 Question 8 Discussion

Service Consumer A sends a message to Service A . There are currently three duplicate implementations of Service A (Implementation 1, Implementation 2, Implementation 3). The message sent by Service Consumer A is intercepted by Service Agent A (1), which determines at runtime which implementation of Service A to forward the message to. All three implementations of Service A reside on the same physical server.You are told that despite the fact that duplicate implementations of Service A exist, performance is still poor at times. Also, you are informed that a new service capability will soon need to be added to Service A that will introduce functionality that will require access to a shared database that is used by many other clients and applications in the IT enterprise. This is expected to add further performance demands on Service A . How can this service architecture be changed to improve performance in preparation for the addition of the new service capability?
B) The Service Autonomy principle is applied to further isolate the individual implementations of Service A by separating them onto different physical servers. When the new service capability is added, the Service Data Replication pattern is applied to give each implementation of Service A its own copy of the data it requires from the shared database.
A) The Standardized Service Contract principle is applied to ensure that the new service capability extends the existing service contract in a manner that is compliant with current design standards. The Redundant Implementation pattern is applied to establish separate implementations of Service A that include duplicate databases with copies of the data that Service A requires from the shared database.
C) The Service Loose Coupling principle is applied together with the Standardized Service Contract principle to ensure that Service Consumer A is not indirectly coupled to the shared database after the new service capability is added to the service contract. The Legacy Wrapper pattern can be applied to establish a new utility service that will provide standardized data access service capabilities for the shared database. D . None of the above.

Not sure if just replicating data will solve the performance issues long-term.

The Service Autonomy principle makes sense here, definitely a good approach.

Wow, I didn't realize duplicate implementations could still lead to poor performance!

I disagree, I think just optimizing the shared database would be enough.

Sounds like separating the implementations onto different servers could help.

I'm leaning towards the Power Platform connector. The question mentions a model-driven application, and the Power Platform seems well-suited for that kind of solution. Plus, it can integrate with Azure services for data migration.

Option B seems like an interesting approach, but I'm not sure if disabling acceleration is the right solution here. I'll need to think this through a bit more.

Hmm, I'm not too familiar with the EOS environment, so I'll have to think this through carefully. Let me review the question again.

I'm a little confused by this question. The solution seems to focus a lot on the integrations, but I'm not sure if that's the only important factor in choosing an IAM solution. I'll have to review my notes and think about the other criteria we discussed in class.
