Azure IoT

IoT Architecture

Device-to-Cloud MessagingData Event / Messages are sent from the hardware device to the cloudSensor readingsTelemetry stream

Generally feeds into some kind of Message Queue for processing

Lambda ArchitectureData Aggregation

Real-Time Processing / Analyticsfast

Batch Processingslow

NOTES:Devices generate events / messages sent to a Queue. In Azure this would be Azure IoT Hub or Event HubsThem event data is sent 2 directionsFor Real-Time processing, like using Azure Stream Analytics and possibly Machine LearningFor Batch Processing, like Azure SQL Database or DocumentDB for archivingThe end result is basically the same for both paths; some kind of database to persist the data for longer term storage and retrievalFinally an application on the other end that will do something with the data.Perhaps reporting like Power BI or just some kind of business app9

Cloud-to-Device MessagingCommand / Messages sent to the hardware deviceInstruction to perform an actionTurn something on: Light, Fan, Open Door, etcStart / Stop gathering telemetry

2-way messaging

MQTT ProtocolMessage Queuing Telemetry Transport

Publish / Subscribe, simple and lightweight protocol

Encryption performed using SSL

Designed for low-bandwidth, high-latency or unreliable networks

Created in 1999 http://mqtt.org

NOTES:MQTT has become a standard protocol for Internet of ThingsOperates over TCP/IP port 1883 reserved for MQTT, and 8883 with SSL / encryption11

Other ProtocolsAMQPAdvanced Message Queuing Protocolhttp://amqp.org

HTTPStandard web protocol

Custom or Device SpecificLegacy or Proprietary

IoT GatewaysSimilar to a Proxy

Provide aggregation point for device communications

Field GatewayLow powered or simple devices may not have capacity to provide security necessary for IoT; maybe no SSL

Protocol GatewayProvides protocol adaptationTranslates from custom / proprietary protocol to one cloud supports; like MQTT or AMQP

Offers a single security attack vector connected to Internet
