In this episode, Clemens introduces Azure Event Hubs as Azure’s high‑throughput event streaming backbone, handling tens of trillions of events per day and exposing a fully managed, standards-based event stream broker that supports AMQP, HTTP, and the Apache Kafka protocol plus SDKs for major languages. He explains the different SKUs—Standard (shared, low-cost), Premium (isolated resources and advanced networking), and Dedicated (for very large sustained workloads)—and describes the architecture of namespaces, event hubs (topics), partitions as replicated logs, and consumer groups that coordinate readers over the log. Event Hubs is positioned not as a queue, database, or generic pub/sub broker, but as a fast, durable buffer for time-ordered event ingestion and replay with configurable retention, with reliability provided by zone-replicated partitions, optional cross-region geo-replication (async or synchronous with RPO‑0), strong virtualized networking and private endpoints, and Event Hubs Capture, which automatically archives incoming events into Avro files in Azure Storage for long-term retention and batch processing.
