After reading our article Security by Design, you’d have a pretty good idea about what the Internet of Things is. For newbies to the technology, let’s have a quick recap. A simple definition of IoT is this:

 “The IoT is a network of Internet-linked devices, vehicles, and appliances that can collect and share data without the need for human interaction.”


IoT devices are pretty nifty. They gather information and send it to a central data server where it gets processed and used for all sorts of handy tasks. It’s not just businesses that benefit from IoT, but also governments, organizations, and regular folks like you and me. You’ll find all kinds of devices that are IoT-ready, like smartphones, laptops, coffee machines, and refrigerators – some even order replacement water filters automatically – Google Home, Apple watches, Fitbits, and more. Basically, if a device has sensors and an Internet connection, it’s part of IoT. People often talk about IoT and Big Data together because IoT generates loads of data, just like Big Data does. You could say that all the information from the Internet of Things is considered Big Data, but not all Big Data comes from the Internet of Things.


The Internet of Things has found its way into many aspects of our lives. Thanks to IoT, we can keep tabs on lost pets, secure our homes with advanced systems, and stay on top of appliance maintenance schedules. For consumers, IoT brings convenience by enabling restaurant reservations, exercise tracking, and monitoring overall health. They can even receive store coupons simply by passing by a business. Businesses leverage the technology to monitor supply chains, gather insights into customer spending habits and feedback, manage inventory levels, and predictively maintain their machines and devices. IoT brings us a whole new level of efficiency and productivity.


The explosion of IoT solutions can be credited to awesome technological advancements. We’ve got these inexpensive and energy-efficient sensors everywhere now.

It’s all these amazing things coming together that have made IoT such a big hit.


The world is facing serious challenges, and it’s time for all industries to turn to IoT for solutions.

  • Take ‘The Climate Pledge’ where big players like Mercedes Benz, Amazon, Microsoft, and Unilever are teaming up to achieve zero net carbon emissions by 2040. They’ve been driven by the increasing wildfires and floods caused by extreme weather events. To make it happen, companies are investing in IoT-based energy and resource management.
  • Governments are also realizing the need to cut down on fossil fuels. Companies like Ford are going all-in on electric fleets, leading to investments in smart grids and smart city planning.
  • The pandemic has pushed us to adopt remote work, telemedicine, and automation of many tasks. Cloud vendors like AWS are catching up by focusing on IoT cloud services, offering communication services and tailored solutions for IoT systems.

All these factors are sparking a wave of applications in the IoT space, from experimental to well-established ones, set to shake up various industries. Let’s take a look at five of the top applications in our world today.


In large enterprises, there are dedicated IT teams responsible for building, maintaining, and monitoring the technology infrastructure.

  • When it comes to security, an IoT-powered solution leverages real-time data to proactively mitigate cybersecurity attacks. It can even prepare incident responses and security policies based on network activity, ensuring a robust defence.
  • Another valuable application of IoT is utilizing customer analytics for informed decision-making. Enterprises now have access to an unprecedented amount of real-time data, enabling them to make data-driven choices like never before.
  • ITIL (Information Technology Infrastructure Library) comprises best practices for managing IT assets and services. These practices focus on aligning IT services with business requirements. With the increasingly complex enterprise infrastructure, where devices communicate with each other, it is crucial to strategically consider IoT integration into the ITIL framework, enriching the library with valuable insights from IoT data.


One of the coolest things about IoT is how it’s transforming our homes into smart havens. Sensors everywhere, controlling the lights, managing resources, and keeping your place secure. It’s like having your own mini smart city right at home. Every single second, we’re seeing 127 new smart home devices connect to the internet. You’ve probably heard of some popular ones like Google Home, Philips Hue Lighting System, or Amazon Echo Plus. With IoT, you can bring all your home gadgets together, from air conditioners and lighting to locks and thermostats, and control them all from your trusty smartphone. Convenience at its finest!


It’s mind-blowing to think that by 2023, an estimated 309 million homes worldwide will be rocking these smart systems. Let’s take a peek at Mark Zuckerberg’s setup, for example. He’s got his own IoT-based smart home system called Jarvis. It’s super high-tech, using fancy natural language processing to understand voice commands. He’s even got internet switches to control appliances. Jarvis takes care of things like adjusting room lighting based on who’s there and playing personalized tunes to set the mood. And let’s not forget the top-notch security. Facial recognition lets the family know who’s at the door. How cool is that?


Supply chain management (SCM) is all about making sure goods get from point A to point B smoothly. It involves managing inventory, fleets, vendors, and maintenance. During the pandemic, supply chains were hit hard, so businesses started looking for ways to make things run better even from a distance. That’s where the Internet of Things (IoT) comes in.

  • The IoT is used in SCM processes in many ways. Shipping companies use trackers to keep an eye on their stuff and find the fastest, most fuel-efficient routes. They can also monitor things like container temperature and humidity using IoT.
  • With IoT, managers can make smarter choices about how things get from place to place, making the supply chain more reliable and resilient.
  • Real-time fleet management keeps everything on track and lets people know if there are any problems along the way.

IoT in fleet management connects vehicles, managers, and drivers, making sure everything runs smoothly. It also takes care of things like vehicle health and following regulations.


 The Internet of Things (IoT) is changing the game in healthcare by creating a more efficient connection between patients, doctors, and pharmaceuticals. Instead of just reacting to medical issues, we can now be proactive.

  • Doctors can attach sensors to patients at home, allowing them to monitor their health remotely. If any parameters go haywire, doctors are immediately alerted, and they can take pre-emptive action. This is especially helpful for high-risk patients, like the elderly or those with chronic diseases.
  • IoT also makes it easier to manage patient medical records and access them. Real-time data is available across different departments, making collaboration and decision-making faster and more effective.
