Queues vs Topics: The Azure Service Bus Showdown

Summary

Azure Service Bus offers two primary transport methods: message queues and topics, with queues allowing single-consumption messaging and topics enabling multiple consumers through subscriptions. The key difference lies in how messages are processed, with queues providing a one-time consumption model and topics supporting multiple independent subscriptions to the same published message. This architectural approach provides flexibility in designing distributed messaging systems, allowing developers to choose the most appropriate transport method based on their specific application requirements.
