The Internet revolutionized how people communicate, what they do, and how they work together. The revolution is not done. The next wave of the Internet will connect machines and devices together into functioning, intelligent systems. These interconnected devices, aka the Internet of Things (IoT), will link machines together with speeds, scales, and capabilities far beyond what people need or use. The IoT of intelligent connected devices will change the world, perhaps more profoundly than today's human-centric Internet. However, figuring out where your application fits into the maze of technologies is truly confusing. This webinar will decode the machine-to-machine (M2M) technology jumble. When does DDS (Data Distribution Service) make sense? How does it compare to MQTT (Message Queue Telemetry Transport)? To the AMQP (Advance Message Queuing Protocol)? To the cloud? These technologies differ drastically; we'll provide a guide to help you navigate. We will then explore some of the applications and reasons that high-performance integrated device systems are choosing DDS, the Object Management Group (OMG) standard for Data Distribution Service middleware. Attendees will learn why DDS is the only technology that delivers the flexibility, reliability, and speed necessary to build complex real-time applications. We will examine why military systems, wind-turbine farms, advanced medical systems, asset-tracking systems and automotive test and safety systems choose to base their designs on DDS. Speaker: Dr. Stan Schneider, Chief Executive Officer

3. What is the Internet of Things?
• Cisco “Internet of Everything”
– …the latest wave of the Internet -- connecting physical
objects…to provide better safety, comfort, and efficiency
• IBM “Internet of Things”
– …a completely new world-wide web, one comprised of the
messages that digitally empowered devices would send to one
another. It is the same Internet, but not the same Web.
• GE “Industrial Internet”
– …convergence of machine and intelligent data…to create
brilliant machines
• RTI “Your Systems. Working as One.”
– …an entirely new utility. As profound as the cell network, GPS,
or the Internet itself. The Internet of Things and the Intelligent
Systems it enables will fundamentally change our world.

32. Fundamental Diff: Brokers vs DataBus
AMQP, MQTT, CoAP
• Centralized Hub and spoke
– Comms route through server
– Web server, broker or ESB
• Server queues messages with
simple QoS (e.g. TCP)
• Simplified discovery
• Server challenges: failover, latency
under load, error recovery
DDS
• Decentralized Peer-to-peer
– Fully embeddable
– No external sftw (e.g., broker)
• Bus shares data with complex QoS
• Discovery challenge
• No single point of failure,
bottleneck, or service
interruptions
