Azure implementation of event processing

If you require receiving and processing millions of events per second, Azure Event Hub is the ideal solution. Typical use cases include tracking and monitoring telemetry collected from an industrial machine, mobile devices, and connected vehicles. For example, in-game events capture in-console applications.

Event Hubs work with low latency and at a massive scale, and serves as the on-ramp for big data: 

The following screenshot is a canonical implementation of event processing on Azure:

The Advanced Message Queuing Protocol 1.0 is a standardized framing and transfer protocol for asynchronously, securely, and reliably transferring messages between two parties. It is the primary protocol for Azure Service Bus Messaging and Azure Event Hubs. Both services also support HTTPS. The proprietary SBMP protocol that is also supported is being phased out in favor of AMQP.

AMQP 1.0 is the result of broad industry collaboration that brought together middleware vendors, such as Microsoft and Red Hat, with many messaging middleware users such as JP Morgan Chase representing the financial services industry. The technical standardization forum for the Advanced Message Queuing Protocol (AMQP) protocol and extension specifications is OASIS, and it has achieved formal approval as an international standard as ISO/IEC 19494.
