IoT Platforms Comparison: AWS, Azure, Google, IBM, Cisco

IoT platforms

IoT (Internet of Things) can be defined as the technology that connects devices or rather “things” to the internet. These things can be air conditioners, headphones, refrigerators, washing machines, smartphones, cars, televisions, and almost everything else we use in our day-to-day lives at home and in the office.

The adoption of these devices has been boosted by IT service desk outsourcing. As a small business or an enterprise decision maker, you do not have to employ experts to provide solutions whenever you have issues with your IoT devices. Instead, you can rely on outsourced IT help desk services, which are more convenient and come with a flat and simple pricing structure.

IoT devices come with a circuit board that has sensors used for connecting them to the internet. Some good examples of IoT devices might include fire detection sensors, elevator accelerometers, humidity and temperature sensors, and pressure sensors, among others.

You can also find IoT services in big machines such as jet engines, meaning that they can be used anywhere and in different projects. However, the most exciting and in-demand IoT projects include self-driving cars, smart retail, smart infrastructure, smart buildings, smart homes, and smart factories, among others.
