words, it is a service which helps you to bring the physical objects

online. This platform will provide you with the services to connect the

devices for a machine-to-machine communication. There is no

specific architecture for IoT; it depends on the solution you are

looking for. For any type of architecture, the following four

components need to be present:

Sensors/actuators

Data Acquisition Systems/Internet Gateway

Edge IT

Data Centre/Cloud

The data that the IoT sensors collect has to pass through the

following four stages, as represented in Table 19.1 as follows:

Stage I – Data

Collection

Stage II – Data

Aggregation &

Conversion

Stage III – Data

Pre-Processing

Stage IV – Data

Management

Data is collected

through

sensors

and actuators

Data from sensors

are collected by

WIFI

or

wired

LANs

and

converted

into

useful information

Edge IT system

does

more

analysis of data

using

machine

learning

and

visualization

technologies

Data passed on to

the data centre or

cloud-based

system

Table 19.1: States of data processing using IoT

Some of the top IoT Platforms are Google Cloud Platform,

OpenRemote, IRI Voracity, Particle, ThingWorx, IBM Watson IoT,

Amazon AWS IoT Core, Microsoft Azure IoT Suite, Oracle IoT, Cisco

IoT Cloud Connect, Altair SmartWorks, Salesforce IoT Cloud etc.

19.2 Nextgen IoT

For any emerging technology, there is always a room for

improvement.
