Azure Event Hubs

What Azure Event Hubs is

Azure Event Hubs is a paid cloud service for handling event streams through the web. Client applications can use .NET, Java, Python, JavaScript, Go, or C. The service includes a schema registry and provides at-least-once delivery. Capacity is offered through Basic, Standard, Premium, and Dedicated plans, with limits that vary by retention, consumer groups, partitions, event hubs, and processing or capacity units. Basic allows one day of retention, one consumer group per event hub, 32 partitions per event hub, and 10 event hubs per namespace. Standard extends retention to seven days and allows 20 consumer groups. Premium allows 90 days, 100 consumer groups, 100 partitions, and 16 processing units. Dedicated also allows 90 days, with 1,000 consumer groups, 1,024 partitions, and 10 capacity units. Basic and Standard use throughput-unit hourly billing; Premium uses processing-unit hourly billing. Dedicated usage is billed hourly with a four-hour minimum. A 30-day trial is available, but no free plan is offered.
