Azure Service Bus and Azure Event Hubs are both messaging services Azure provides, but they are designed for different use cases. Azure Service Bus is an enterprise messaging service that is used to decouple applications and services from each other. It provides load balancing, data routing, and transaction coordination features. On the other hand, Azure Event Hubs is a data streaming platform designed to process large amounts of data in real-time.
One key difference between the two services is the way they handle data. Azure Service Bus is optimized for message-based communication, while Azure Event Hubs is optimized for event-based communication. This means that Azure Service Bus is better suited for scenarios where messages need to be reliably delivered in a specific order, while Azure Event Hubs is better suited for scenarios where many events need to be processed in real-time.
Another difference between the two services is their pricing model. Azure Service Bus charges based on the number of messages sent and received, while Azure Event Hubs charges based on the number of events processed. This means that Azure Service Bus is better suited for scenarios where the volume of messages is relatively low, while Azure Event Hubs is better suited for scenarios where the volume of events is high.
Azure Service Bus vs. Azure Queue Storage
Azure Service Bus and Azure Queue Storage are messaging services Azure provides, but they have different feature sets.
