    Service Bus Queues.

    See the note about sessions here;

    If a message has the session ID property set, then Service Bus uses it as the partition key. This way, all messages that belong to the same session are handled by the same message broker. Sessions enable Service Bus to guarantee message ordering as well as the consistency of session states.

    @Riddhi Gupta

    To add further among the above azure services you mentioned, Service Bus follows the First In, First Out (FIFO) queuing model.

    Service Bus queues offer FIFO message delivery to one or more competing consumers. That is, receivers typically receive and process messages in the order in which they were added to the queue. And, only one message consumer receives and processes each message.

    see- https://learn.microsoft.com/en-us/azure/service-bus-messaging/service-bus-queues-topics-subscriptions

    On the other hand, App Service, Notification Hub, and Event Hubs do not follow the FIFO queuing model.

    App Service is a platform for building web and mobile apps, Notification Hub is a push notification service, and Event Hubs is a big data streaming platform. These services have their own unique messaging models and are not designed for FIFO queuing. Please let us know if further query or issue remains.

    Please accept as "Yes" if the answer provided is useful , so that you can help others in the community looking for remediation for similar issues.
