The document discusses the Internet of Things (IoT) and how AWS IoT works. IoT involves connecting physical devices to the internet and collecting real-time data from various sensors. AWS IoT provides a scalable cloud platform that allows IoT devices to securely connect and interact with AWS services. It supports massive data volumes from connected devices and includes features like a device gateway, device registry, device shadows, and rules engine.

3.  The internet of things (IoT) is the network of physical devices,
vehicles, buildings and other items—embedded with electronics,
software, sensors, actuators, and network connectivity that enable
these objects to collect and exchange data.(From Wikipedia)
 The Internet of Things links the objects of the real world with the
virtual world, thus enabling anytime, any place connectivity for
anything and not only for anyone. It refers to a world where physical
objects and beings, as well as virtual data and environments, all
interact with each other in the same space and time.(From European
Commission: Internet of Things )

5.  Made up of sensors and smart devices.
 Real-time data will be collected.
 Sensors use low power and low data rate.
 Sensors are grouped according to their purpose and data type(Eg.,
environmental sensors, military sensors, body sensors, home
sensors)

6.  It must support massive data produced by sensors.
 Provides reliable services .(MQTT , CoAP-Protocols)
 It should be integrate different type of networks in one single IOT
platform.

7.  Analysis and management of data
 Security control(ACLs, encryptions, identity access)
 Billing reporting

8.  Application can be classified based on types of network availability,
size, heterogeneity, as well as real time and non real time application.
 Examples:
 E-Health, personal security, road safety, toll payment, real time traffic
monitoring and many more......

9.  Privacy -- will be a huge issue when implementing IoT
 Cloud is important -- IoT applications require end-to-end solutions
including cloud services
 Sensing is complex -- sometimes it is difficult to connect sensors
with devices and internet
 Identity – it is difficult to identify data and devices in huge data streamed.

10.  It is scalable and managed cloud platform that allows devices to
connect securely and interact with AWS services.
 AWS IoT makes it easier to build IoT apps
 AWS IoT platform allows you to collect, store, analyze, and take
actions against large volumes of data streaming from your connected
devices.

12.  Device Gateway – The AWS IoT Device Gateway is a highly
scalable managed service that enables devices to communicate
securely with AWS IoT.(MQTT & HTTP).
 Device Registry – Device Registry stores metadata about the
devices and acts as an unique identity store of devices.
 Device Shadows – Device Shadows is a unique capability provided
as part of the AWS IoT platform that creates a virtual device, or
shadow, of the device that contains its latest state.
 Rules Engine – The AWS IoT Rules Engine transforms and routes
incoming messages from devices to AWS services based on
business rules you create.
