Understanding IoT Platforms: A Non‑Technical Overview

Whether you are new to IoT or an experienced veteran, you may have heard the term “IoT Platform”. Last year there were over 300 IoT platforms, and the number continues to grow rapidly (now reportedly over 700). The IoT platform market’s compound annual growth rate (CAGR) is 33% and is expected to reach $1.6 billion in 2021.

IoT platforms are a key component of the IoT ecosystem, but many people are still unclear about what an IoT platform actually is or how they differ from one another.

In this article I provide a simple, non‑technical explanation of IoT platforms: what they are, how enterprises use them, and important considerations when choosing among the many options.

What is an IoT platform?

To understand what an IoT platform is, you first need to understand the components of a complete IoT system. My previous post “How does an IoT system work?” is a good learning resource, but I will summarize it briefly here.

Hardware : sensors or devices that collect data from the environment (e.g., a moisture sensor) or act on it (e.g., irrigating crops).

Connectivity : a method for the hardware to transmit data to the cloud and receive commands, sometimes via a gateway or router.

Software : cloud‑hosted software that analyzes the collected data and makes decisions (e.g., detecting rain from humidity data and telling the irrigation system not to turn on).

User interface : a way for users to interact with the system, such as a web dashboard showing humidity trends and allowing manual control.

IoT platforms are the supporting software that connects everything in an IoT system. They facilitate communication, data flow, device management, and application functionality.

The platform resides in the third layer of the architecture, often considered the fourth component above. With many hardware types and connectivity options, the platform provides the glue that makes everything work together.

IoT platforms help:

Connect hardware

Handle different communication protocols

Provide security and authentication for devices and users

Collect, visualize, and analyze data

Integrate with other web services

When should your business adopt an IoT platform?

Because IoT is a system of systems, organizations that have expertise in all related areas are rare. IoT platforms help enterprises overcome technical challenges without having to handle everything internally.

For example, if your business is good at building hardware and wants to make it “smart”, you can use an IoT platform instead of hiring software developers to build everything from scratch, saving time and cost.

However, there is a trade‑off. While IoT platforms can save time, their usage or subscription fees may increase over time, potentially making the long‑term price higher. Nevertheless, they still offer a significant reduction in upfront capital expenditure.

A cheap IoT platform up front may cost you time later; the less work you have to do yourself, the more time you save overall, though you may need to invest time in other areas.
