Event Hub vs IoT Hub

Event Hub - intro

• highly scalable data streaming platform
• publish-subscribe capabilities
• serves as the "on ramp" for Big Data

Event Hub - use cases

• Application instrumentation
• UX/workflow processing
• IoT scenarios
• Event-driven systems

Event Hub - overview

Event Hub - caveats

• single event/batch(!) limited to 256KBs
• authentication with a shared/common SAS token
• no bi-directional communication
• when hits a limit, throttling occurs
• single TU = ingress 1MB or 1K events, 2MB egress
• only 5K concurrent connections on AMQP

IoT hub - intro

• multiple device-to-cloud or cloud-to-device communication options
• built-in routing to other Azure services
• queryable store for device metadata
• per-device keys
• extended monitoring
• file upload capability
• device twins

IoT Hub - architecture

Iot Hub - device twins

Pricing

EH: 19 EUR -> 12M events / month(1TU what is 1k/1MB events per sec)
