Technology has revolutionized how we do everything including working from home, ordering food with a click on our mobile, getting entertained, and accessing information. Together with food, water, and a roof over our heads, internet access has become one of the most basic human needs.

Although it poses both a boon and bane in our lives, we and the economy can't imagine living without technology. Here we will discuss what makes up the four pillars of IoT to understand how it benefits us, the digital and physical world.

What is IoT?

Before discussing the four pillars of IoT in detail, let’s first look at what IoT is. The Internet of Things, also known as IoT, is a network of "things" embedded and closely working with software and other technologies that make exchanging data and connecting with other systems and devices via the internet possible.

They can be ordinary house devices like washing machines to the phone in your pocket to more advanced and sophisticated machinery used by industries in their processes.

The Four Pillars of IoT

  • Device

The first of the four pillars of IoT is the device. This device can be anything from your phone to medical devices used in hospitals, cars, and other electronic appliances.

It is any form of hardware capable of transferring data from one point to another using the internet. To stay connected, such devices will need a wireless network to be able to support running on one primary network.

  • Data

One of IoT's main objectives and purposes is data gathering and storing. Such processed data will help improve the application and functionality of different devices and software, making data the second of the four pillars of IoT.

You can see this pillar in action clearly in exercise applications that track any user's movement in order to come up with pertinent data that will help them track their fitness goals.

  • Analytics

The third of the four pillars of IoT is analytics, which makes it possible for each data collected to be analyzes efficiently and correctly. Analytics within a device makes a thing powerful and valuable in any individual's life since it is the aspect that makes any device perform the data transmitted.

Returning to our exercise application example, once data is collected, analytics happen as soon as you see how many steps you made in a day and how many calories burn because of it.

  • Connectivity

The last of the four pillars of IoT is connectivity which allows all the other three pillars to work in conjunction harmoniously. Connection makes it possible for the data to be transmitted and analyse correctly.

No interruption in connectivity is vital to maintain the flow of real-time data processing and analysis. Optimised processing and data use in different systems and software are impossible without it. Data analyse can also have the problem of inaccuracy and loss because of a poor connection.

Who can benefit from the Four Pillars of IoT?


One sector that can benefit significantly from IoT is manufacturing, from production monitoring to proactive maintenance and other logistic problems.

They can use sensor devices to lessen the failure in their production line leading to more minor and fewer problems in the long run. With fewer problems, there is the benefit of reducing operating costs and improving performance management.


The benefit of IoT in the automotive industry's processes doesn't end in the production line but extends to improve end-buyer or user's performance.

IoT is embedded in the car's technology, which can alert any driver if there is a problem in the engine that can easily be remedied to avoid costly repairs in the end. This benefit is especially true for smart cars with more advanced in-car software.

Transportation and Logistics

Since the world is globalized, transportation and logistics go far beyond just in-country deliveries and transfers. Using IoT in the transportation sector can alert any pilot or driver of the weather condition affecting the delivery or flight time so that they can quickly reroute.

For logistics, IoT is embedded in the track-and-trace features available for all our deliveries.


In the realm of retail, IoT is ingrained in every logistical process, from inventory to customer experience improvement to the supply chain. By using IoTs to optimize their system, they get the benefit of reduced overall operation costs. IoT can alert them of low stocks, and it can also aid in product promotion to targeted audiences.

Public Sector

IoT in the public sector is heavily utilized in providing utilities like water and electric connection and other service-oriented offices.

One example of the use of IoT in utility distribution comes in notifying their users during outages or shorter interruptions for repairs when it comes to their water or electric connection.


IoT use in healthcare ranges from logistics to accounting in any healthcare service provider. IoT lets doctors or nurses know the locations of the closest patient-assistance assets like spare rooms or wheelchairs to assist their patients. IoT makes this feat easier, especially for advanced hospitals.


Safety is a concern across all industries, from manufacturing to healthcare providers concerned with giving their workers improved safety measures. Many workers in hazardous environments like chemical and power plants, mines, or gas fields need to be alerted if problems occur and IoT sensors available in applications make that possible.

It is also embedded in devices like the exercises and steps tracker to make anyone understand their health better.

Final Thoughts

The four pillars of IoT, working cohesively with each other, dictate the success and effectiveness of IoT. Each aspect is beneficial to ensuring a great experience for end-users.

Alternatively, if one is without the other, IoT can be deemed ineffective and will lead to problems that will stop data from being sent and analyzes within the system.
