You are designing an Azure application. The application includes services hosted in different geographic
locations. The service locations may change.
You must minimize the cost of communication between services.
You need to recommend an approach for data transmission between your application and Azure services. The
solution must minimize administrative effort.
What should you recommend?
A.
Azure Table storage
B.
Service Bus queue
C.
Service Management API
D.
Azure Queue storage
Explanation:
The cost of ACS transactions is insignificant when performing messaging operations against Service Bus
queues. Service Bus acquires one ACS token per a single instance of the messaging factory object. The token
is then reused until it expires, after about 20 minutes. Therefore, the volume of messaging operations in
Service Bus is not directly proportional to the amount of ACS transactions required to support these operations.

Agreed
You can envision an eventual migration from queue-based point-to-point communication to a message exchange pattern that enables seamless integration of additional receivers (subscribers), each of which receives independent copies of either some or all messages sent to the queue. The latter refers to the publish/subscribe capability natively provided by Service Bus.
