In 2020, for the first time, the number of active connections driven by IoT services (connected cars, smart home devices, connected industrial equipment) was higher than non-IoT connections  (smartphones, laptops, and computers). And according to the same report, by 2025, there will be 30.9 billion actively connected internet of things devices. This is because the Internet of Things allows you to automate many processes both in production and in our home and significantly simplify everyday operations. Today we will consider the most popular IoT platforms, their impact on business, and comparative characteristics.

    What is the Internet of Things Cloud Platforms?

    The Internet of Things includes several cases at once:

    • Devices themselves go online and interact with each other.

    • An M2M  way of connecting, that is, machine-to-machine, without human intervention.

    • Big data that devices generate. Data that can (and should) be collected, analyzed, and further used to improve comfort or make business decisions.

    IoT is used in any industry where something needs to be automated, but it is especially active in the agricultural sector, production, logistics, and Smart City.

    IoT Cloud is the network that supports all IoT devices. In other words, it is the basic infrastructure that includes the servers and storage required to collect and process real-time information and the services and standards that operate to connect devices.

    Why are Internet of Things Platforms Essential?

    The Internet of Things (IoT) plays a crucial role in establishing intelligent interactions between people and surrounding entities and objects. When we talk about the high-quality and efficient collection and analysis of large amounts of data, IoT is irreplaceable. Such data is very difficult to process and store physically, which is why more and more companies are switching to cloud computing.

    The Internet of Things cloud platform allows you to increase the productivity of processes associated with collecting, processing, and storing data, minimizing the associated costs. Here are some other significant benefits that users can get when handling IoT Platforms:

    • High reliability and security standards of cloud storages

    • Expansion of the business infrastructure following the requirements and goals of the company

    • Accelerate workflow and reduce downtime with near-real-time insight

    • Scan and update any application included in the infrastructure at any time

    While deploying custom cloud infrastructure is invaluable to a business, in particular the ability to customize the system to meet all the needs of the business, in some cases, it makes sense to use a ready-made solution. Let’s consider a list of the 10 top IoT platforms available today.

    #1 AWS IoT Core

    Amazon dominates the cloud services market. They were the first to provide such solutions, offering them back in 2004. Amazon Web Service IoT Core provides cloud platforms on demand to various clients, private companies, enterprises, the public sector, and even governments. AWS is considered the best IoT cloud platform in 2021.

    If the subject of the Internet of Things and cloud platforms is still a mystery to you, here are the most pressing questions from customers and answers to them.

    1. What are the key features of an IoT cloud platform?

    There are a large number of paid and open-source cloud platforms. Many large IT companies such as Microsoft, IBM, or Google provide a reliable and scalable solution. At the same time, network operators like AT&T, Vodafone, and Verizon also offer some products for the Internet of Things. But despite the diversity on the market, all cloud platforms for IoT have clear goals: configuring and managing networks, connecting and managing devices, collecting, analyzing, introducing, and visualizing data.

    2. How does an IoT cloud platform differ from a traditional cloud infrastructure?

    The traditional cloud computing model aims to provide on-demand access to hardware and software resources so that data can be prepared quickly and easily and presented with minimal effort. The Cloud IoT platforms use the same model but in a more advanced form. Thus, it increases the number of resources and capacity so users can receive larger volumes of data. In addition, cloud IoT platforms provide intelligent data processing (mainly through machine learning) and provide the opportunity to manage them effectively. 

    3. What are the key factors to consider when choosing IoT cloud platforms?

    Each system has its pros and cons. The choice should largely depend on your business’s needs. The main factors to consider are scalability, reliability, customization, support, architecture, technology, security, and price. When ready-made solutions do not fit the needs of your business, it is more expedient to design a custom IoT cloud platform to connect and manage all devices in the infrastructure.

    4. Where is IoT used?

    The Internet of Things is a network of physical objects, sensors, software, and other technologies built-in to connect devices to a shared infrastructure, manage them, collect and analyze data. IoT is widely used in many areas and industries, including manufacturing, healthcare, agriculture, energy management, military, environmental monitoring, smart homes, transportation, logistics, and more.

    5. Is IoT the future?

    IoT is rapidly developing, and soon more and more services and devices working with this technology will become available. The increasing flexibility of networks, the widespread use of artificial intelligence, and large-scale automation will contribute to the fact that the Internet of Things will be highly integrated into our lives.


    IoT platforms are good at helping businesses of all sizes automate processes, gather and analyze data efficiently. Companies working with vast volumes of information can significantly increase their productivity by integrating cloud solutions into their infrastructure. It is worth noting that many of the popular IoT cloud platforms are relatively easy to use. But the high prices can be a significant disadvantage, especially if you need to connect a large number of devices. In this case, the development of a custom IoT app is a reasonable and effective solution.
