COMPLEX SELECTION CRITERIA OF CLOUD GATEWAY CHOOSING Authors: Kurdecha V.V., Ishchenko I.O., Zakharchuk A.G.

What is IoT? The Internet of Things (IoT) is a system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.

What is cloud gateway? A cloud gateway is a hardware- or software-based appliance located on the customer premises that serves as a bridge between local applications and remote cloud-based services.

Cloud gateway is the missing piece in the puzzle It connects the core network with the access and edge network; It connects the cloud traffic to the end-users; It also connects between different clouds/datacenters (different locations and different providers).

Architecture of our Solution

Where is Cloud Gateway? IoT reference architecture (from IoT Hub documentation)

IoT architecture with IoT Hub

Each device has two endpoints to interact with IoT Hub D2C (device to cloud) : the device uses this endpoint to send messages to the cloud both as telemetry data, outcome for a received command or request for execution; C2D (cloud to device) : the device receives commands on this endpoint for executing the requested action. The IoT Hub generates a feedback at application level to confirm that the command is acquired by the device and it’s going to be executed;

What IoT Hub also has Identity registry; Monitoring information; Device identity management;

AWS IoT data services

SDKs : languages and platforms supported IoT Hub: .Net SDK; Java; NodeJS; C. AWS IoT: C; NodeJS.

Security and Authentication The connection established between devices and IoT Hub is TLS (Transport Layer Security) based. The authentication is provided by IoT Hub verifying a SAS (Shared Access Signature token) token. AWS IoT relies on TLS protocol so that the communication with the message broker is encrypted and the client is authenticated using the mutual authentication.

Messages : exchanging data on the wire A message in the IoT Hub has an opaque payload to carry data in user defined formats (for example binary, XML, JSON and so on). The AWS IoT enables the interaction with thing shadows. The thing shadow is a JSON document used to store and retrieve current state information for a device.

Prices, Quotas and Throttling IoT Hub unit (500 devices); The AWS IoT pricing is based on million messages exchanged quota.
