You are developing a sales application that will contain several Azure cloud services and will handle different components of a transaction. Different cloud services will process customer orders, billing, payment, inventory, and shipping.
You need to recommend a solution to enable the cloud services to asynchronously communicate transaction information by using REST messages.
What should you include in the recommendation?

A. Azure Service Bus
B. Azure Data Lake
C. Azure Traffic Manager
D. Azure Application Gateway

Show Suggested Answer

Suggested Answer: A 🗳️
Asynchronous messaging can be implemented in a variety of different ways: with queues, topics, and subscriptions. Azure Service Bus supports asynchronism via a store and forward mechanism.
Service Bus is a transactional message broker and ensures transactional integrity for all internal operations against its message stores. All transfers of messages inside of Service Bus, such as moving messages to a dead-letter queue or automatic forwarding of messages between entities, are transactional.

It says REST messages. not sure if service bus uses REST messages. Could it be Azure Application gateway? One way of implementing microservices architecture is to hit the other api directly from your code to get required data. Bad way to implement it but still an option.

I'm agree with you anyway exists rest protocol to send and receive messages in servicebus.. but could be a microservices communication via API gateway, I think Service bus is the best one.
