Is your MQTT broker IoT ready?
The document discusses the readiness of MQTT brokers for IoT applications, highlighting challenges and use cases in M2M communication, and the importance of efficient protocols for connectivity. It emphasizes the benefits of MQTT over HTTP, such as low latency, push delivery, and the need for enhanced capabilities beyond MQTT at both device and broker levels. The document also encourages the adoption of open-source solutions like Eclipse Kura to address interoperability and development speed in the rapidly evolving IoT landscape.

- 20. MQTT is OK… but NOT ENOUGH
- 21. What’s beyond MQTT? At the Device Side (client)… • Transport Service –Transport Service Abstraction –Credentials & Authentication management –Provisioning 6
- 22. What’s beyond MQTT? At the Device Side (client)… • Data Services – Manages remote connectivity and reconnect policies – Manages message queuing with priority – Manages message store while disconnected and resume publishing on reconnects 5
- 23. What’s beyond MQTT? At the Device Side (client)… • Cloud Services – Data model for telemetry applications – Topic partitioning across applications – Compression – Birth, Death & App certificates – Request and Response message exchanges – Simplified code for remote resource management 4
- 24. What’s beyond MQTT? At the Broker (server)… • Broker Plugin – Enforces Authentication – Enforces Authorization Topic ACLs – Enforces Account Policies – Tracks User Logins 3
- 25. What’s beyond MQTT? At the Broker (server)… • Device Connectivity – Tracks Device Connectivity – Update Device Status • Data Store – Store messages on IoT noSQL BigData DB 2
- 26. What’s beyond MQTT? At the Broker (server)… • Rules Engine Bundle – Inspect messages, check rules and trigger actions • A-MQ Cluster Support & Protocol translation • Custom Bundles 1
- 27. A-MQ IoT Challenges •A-MQ instances exposed on the Internet for device direct connectivity • Scale on number of connections not just number of messages ESB scenario IoT scenario
- 28. Recommendations • Protect thebroker instances – Firewall configuration, secure A-MQ connectors, SSL enforcements (i.e. <sslContext>), – Configure broker cluster for reliability for the creation of a network of brokers 6
- 29. Recommendations • Consider SSLTermination – Keep it off-broker, as a different SSL-proxy node decoding SSL-2-noSSL 5
- 30. Recommendations • OSGi isyour friend, respect its architecture ! – Deploy Consumers closer to the Broker (no messages over TCP) – Use “vm” connector (direct mem links) 4
- 31. Recommendations • Apply GeneralA-MQ Tunings to configure a Network of Brokers https://access.redhat.com/documentation/en- US/Red_Hat_JBoss_A- MQ/6.0/html/Tuning_Guide/files/PersTuning- Horizontal.html 3

- 33. Recommendations • MQTT Tuning –Nio (decoupling java threads from connections) – Disable JMX due to large number of Topics; Monitor using advisory messages (advisorySupport=TRUE in AMQ.XML) – Increase Durable Topic Prefetch for bulk msg batch processing (activeMQSubscriptionPrefetch) 1
- 34. Recommendations • From ActiveMQ5.11, try virtual-topic-subscriptions – Set a pool of subscribers – Send a message in round-robin to just one of them rather then towards them all (as by default publish-subscribe) 0
