What is Io. T? The Internet of Things (Io. T) 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 humanto-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? Io. T reference architecture (from Io. T Hub documentation)

Io. T architecture with Io. T Hub

Each device has two endpoints to interact with Io. T Hub • D 2 C (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; • C 2 D (cloud to device) : the device receives commands on this endpoint for executing the requested action. The Io. T 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 Io. T Hub also has • Identity registry; • Monitoring information; • Device identity management;

AWS Io. T data services

SDKs : languages and platforms supported • Io. T Hub: 1. 2. 3. 4. . Net SDK; Java; Node. JS; C. • AWS Io. T: 1. C; 2. Node. JS.

Security and Authentication • The connection established between devices and Io. T Hub is TLS (Transport Layer Security) based. • The authentication is provided by Io. T Hub verifying a SAS (Shared Access Signature token) token. • AWS Io. T 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 Io. T Hub has an opaque payload to carry data in user defined formats (for example binary, XML, JSON and so on). • The AWS Io. T 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 • Io. T Hub unit (500 devices); • The AWS Io. T pricing is based on million messages exchanged quota.

Conclusions • Complex selection criteria of cloud gateway choosing was provided. • Io. T hub and AWS Io. T was compared; • The results of this research was used in the startup;
