AWS Internet of Things (IoT) is a managed cloud platform that can support billions of devices and trillions of messages, and can process and route those messages to Amazon Web Services endpoints and to other devices reliably and securely. In this session we look at patterns and architectures for developing connected applications using Amazon Web Services IoT platform. We will dive into demo applications that tie together physical IoT devices, web browsers, identity providers, and mobile devices to create smart, connected applications using Amazon Web Services.

Any device can connect securelyAnyone can connect a device Getting started is easy
“Securely connect one or one-billion devices to AWS,
so they can interact with applications and other devices”

10. Protocols – MQTT
MQTTS vs HTTPS:
• 93x faster throughput
• 11.89x less battery to send
• 170.9x less battery to receive
• 50% less power to keep connected
• 8x less network overhead

• OASIS standard protocol (v3.1.1)
• Lightweight, pub-sub, transport protocol
that is useful for connected devices
• MQTT is used on oil rigs, connected
trucks, and many more sensitive and
resource-sensitive scenarios.
• Customers have needed to build,
maintain and scale a broker to use
MQTT with cloud applications

17. Protocols – MQTT – Keep Alive
PINGREQ
PINGRESP
Although TCP/IP in theory notifies you when a socket breaks, in practice, particularly on
things like mobile and satellite links, which often “fake” TCP over the air and put
headers back on at each end, it’s quite possible for a TCP session to “black hole”, i.e. it
appears to be open still, but in fact is just dumping anything you write to it onto the floor.
