What we think about at AWS • Scale • Security • Reliability • Evolution 18
Scale It’s What We Do For details, see any other talk at re:Invent 19
Scale: MQTT • A common question “Why should I use MQTT? I’d rather just open a socket and write!” • Common encapsulation and routing framework • Allows common messaging infrastructure • DIY payload format • AWS deals with secure scaling, so you can concentrate on your device 20
Security • A major pain point in early IoT systems • A major motivator
 for AWS • Cloud skills carry over

 With each of these toys, the Bluetooth connection had not been secured, meaning the researcher did not need a password, pin or any other authentication to gain access. Little technical knowhow was needed to hack into the toys to start sharing messages with a child. Typical Recent Press 22

Reliability Achieving reliability in a device is different than in the cloud • You can��t fail-over to another processor • You can’t expect a god-like human to rescue it • It’s in amongst regular humans, who do the strangest things • Code coverage is never good enough 24
