You are designing a sales application composed of multiple Azure cloud services that handle different parts of a transaction (orders, billing, payments, inventory, shipping). You need to enable asynchronous exchange of transaction information using XML messages between these services. Which Azure service should you include in your recommendation?

Azure Service Bus is the correct choice because it is a fully managed enterprise integration message broker. It supports asynchronous messaging, which is crucial for decoupling services in a distributed application like the sales system described. Service Bus queues and topics are ideal for exchanging XML messages between different services (orders, billing, payments, etc.) reliably and asynchronously, ensuring that services can process information independently without direct dependencies. Azure Service Fabric is a platform for building and managing microservices, not primarily a messaging service. Azure Notification Hubs is designed for sending push notifications to various platforms. Azure Traffic Manager is a DNS-based traffic load balancer that distributes traffic across global Azure regions. These services do not fulfill the requirement for asynchronous XML message exchange between application components.
