The below image shows our four-stage architecture of the IoT system.

• In the first stage, data is collected and converted into useful data.
• In the second stage, data is converted from an analog form to the digital form.
• In the third stage, Edge IT system performs more analysis of data.
• In the fourth stage, the data which requires more processing and doesn’t need immediate processing will be passed on to the data center or cloud-based systems.

Examples of IoT (Internet of Things)

• Smart home systems are examples of an IoT application. Amazon Echo is the most popular one.
• Smartwatches which allow text messages and phone calls are also an example of IoT applications.
• Fitbit is also an example of IoT devices.

Types of Internet of Things Platforms:

• End to end
• Connectivity
• Cloud
• Data

Some Facts About These Platforms

• The primary function of the IoT platform is to act as middleware or as plumbing to connect devices or applications to another end. IoT contains a mixture of functions like Sensors & controllers, a gateway device, communication network, data analyzing & translating software, and end application service.
• IoT cloud platform can handle huge data volume from devices, customers, applications, websites, and sensors and take actions to give a real-time response.
• How to select the best Internet of Things platform depends on the requirements of a company for hardware, real-time access, custom reports, budget, development skills, and the business model.
