Enable Cloud Services for Asynchronous Communication with XML Messages
Question
You are developing a sales application that will contain several Azure cloud services and 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 XML messages.
What should you include in the recommendation?

Asynchronous messaging options in Azure include Azure Service Bus, Event Grid, and Event Hubs.
https://docs.microsoft.com/en-us/azure/architecture/guide/technology-choices/messagingTo enable the different Azure cloud services in a sales application to communicate transaction information asynchronously using XML messages, the recommended solution is Azure Service Bus (Option C).
Azure Service Bus is a fully managed messaging service in Azure that enables reliable asynchronous communication and transfer of data between applications and services. It supports different messaging patterns such as publish/subscribe, request/response, and message queuing.
Here are some reasons why Azure Service Bus is the best option for this scenario:
- Asynchronous Communication: Azure Service Bus supports asynchronous communication, which means that the services can send and receive messages independently without waiting for a response. This makes the communication more efficient and responsive.
- XML Message Format: Azure Service Bus supports XML messages, which is the required message format in this scenario.
- Scalability: Azure Service Bus can handle high volumes of messages and can scale up or down as needed to accommodate changes in workload.
- Message Queuing: Azure Service Bus supports message queuing, which enables reliable message delivery even when services are temporarily unavailable.
- Security: Azure Service Bus provides various security features such as access control, authentication, and encryption to ensure the privacy and integrity of messages.
Azure Service Fabric (Option A) is a platform for building microservices-based applications. While it provides messaging capabilities, it may be overkill for this scenario, as it is a more complex solution than Azure Service Bus.
Azure Data Lake (Option B) is a data storage and analytics service, not a messaging service. It is not suitable for this scenario.
Azure Traffic Manager (Option D) is a traffic routing service that enables automatic failover and load balancing of traffic between different endpoints. While it can help optimize traffic, it is not a messaging service and is not relevant for this scenario.
Therefore, the correct option is C. Azure Service Bus.
