Ø Cloud computing provides shared pool of configurable computing resource to end users on demand

Ø  Three service modelsq  IaaS (Infrastructure as a Service): virtual machines, storage,

network …

q PaaS (Platform as a Service): execution runtime, middleware, web server, database, development tool …

q  SaaS (Software as a Service): email, virtual desktop, games …

Virtual“Thing”/Shadow

Ø A Thing in AWS IoT has a “shadow”q  a JSON document that is used to store and retrieve

current state information for a device.•  E.g. Battery level, Connectivity, data

q  Shadow is a special topic in AWS IoT

Ø Certificates and policyq Authentication, Securityq Permission and roles

Project0:AWSIoTØ  Create Your AWS accountØ  Setup your things with certificates and policyØ  Publish and subscribe a topic

q  Update your thing’s Shadow with AWS IoT Test Console•  See tutorial

q  Use your computer as a “Thing” to update your thing’s Shadow •  Install AWS IoT SDK, copy the certs, modify the code•  Publish message to your Shadow Topic from your computer

q  Publish and Subscribe on your computer•  Publish a message to a topic in one client from your PC•  Subscribe to the same topic in another client from your PC•  Hints: the “clientID” cannot be the same for the two client. The two

clients can share the same certs. You can use the shadow as the topic.•  (You should see one terminal sends massage, and another terminal

receives that message)Ø  Email your results (inline with some screenshots, you don’t need to

write a report) to dairuixuan@wustl.edu
