A relatively new area of IoT development is only gaining its popularity and relevance. People connect cars, portable devices at home, creating an entire ecosystem of data that developers need to work with. The pioneers of this development have already overcome some difficulties, some just discovered and are working on them. Before becoming an IoT developer, you should learn about these difficulties and know what you are going to deal with in the process.

What Does Await for IoT in the future?

The Internet of Things is a new stage in the development of the Internet when more things are connected to it than people. IoT connects the objects around us to a computer network. They exchange information with each other and work without human intervention and in real-time. In fact, it is the Internet, a new real world.

The Internet of Things promises to change the way whole industries approach their business. This innovation requires the business to both fully digitalize internal processes and change business models for better UX. IoT users are already becoming more and more all over the world, from China to the USA and analysts' forecasts call these processes only the beginning of the development of new technology. The concept itself takes the first place among the predictions of futurologists, but its peculiarity is that it has already begun to be realized.

To hire IoT application developer, you need the following points within the company:

Connected Products: A company can develop new IoT devices and services and combine them into one ecosystem (for example, Apple does this by creating iCloud to upload all the information from user devices there, thus linking them.)

Connected Business Processes: A company can use IoT to improve its business processes.

What are the IoT Applications in different industries? We can already name several areas that use IoT Applications in their business processes.

Smart Home

More and more companies are becoming involved in the creation of smart homes, as demand increases among consumers. Major market players such as Philips and Belkin are already actively occupying a niche, but the area still waits for new startups for further development.

Smart City

The explanation of the meaning is in the concept itself. The concept of a smart city consists of water distribution, waste management, traffic management, and environmental monitoring. Such industrial IoT will improve the quality of citizens’ life, get rid of old problems and make cities safer for life.


Devices that can be interconnected are the most popular for potential buyers.

Connected Car

This application requires powerful networking, so this technology is closely related to the deployment of 5G technology.

Connected Health

Already, the development of new remote monitoring equipment has great potential and will certainly have its customers. The healthcare area in particular needs IoT applications.

Smart Farming

Most farming processes can be monitored using IoT, which would reduce the time and other resources spent on growing crops.

In the future, the business will have an even more serious approach to IoT. Predictive maintenance will be improved by several more levels, which will entail an increase in technology investment. Other predictions also include gaining voice by all IoT devices. Virtual assistants will become part of the smart device itself, as voice control will improve the technology. We must not lose sight of the impact of AI on the development and implementation of IoT technology. Internet of Things creates a huge amount of information. Analysis and outgoing data will be difficult to regulate by a human, therefore only the combination of these two technologies will raise them to the next level of development in the future.

5 pitfalls of IoT Developers that You Can Learn From

As the Internet of Things grows, so does the demand for programmers. This suggests what opportunities will open for them in the coming years. Let's talk about what you need to know before deciding to become an IoT developer.

Basic knowledge of languages

The Internet of Things is so widespread that a developer can choose a programming language to his liking. Low-level assembly or C / C ++ programming is needed for embedded systems.

High-level languages ​​such as Node.js and Java will be a great start for beginners in IoT programming. They have a low entry threshold and also, have useful features, such as automatic memory deallocation. It is also important to be able to understand the SoC directory and understand how the sensors interact with the DAC.


This problem is raised every time it comes to IoT. With so many connected devices, it can be difficult for users to protect their personal data and application patterns. The more devices are connected, the more vulnerabilities and IoT security threats. Among them are attacks on cloud services that store large and often confidential amounts of data. This makes them an attractive target for hackers who are very inventive in their search for new attack vectors for centralized services. In the event of hacking of a cloud provider alone, the damage can range from 50 to 120 billion dollars.

Data validity

Data stored on IoT platforms cannot be completely trusted outside the scope of responsibility of one owner since it is not possible to verify that they have not been changed before being sent, sold or used by other parties.

Large companies such as Uber and Lyft do not have a solution that allows them to share reliable map data or travel data; they found another way: to collect and store such data sets independently of each other.


Another topical issue of IoT is user privacy. And it's not only about the possible theft of data by hackers, but also about a violation of the privacy of the consumer. Enhanced corporate transparency is required to ensure the invulnerability of user data.

Lack of control system

Another problem is that the IoT industry faces is its insufficient scaling - if forecasts regarding the number of connected devices shortly come true, it is difficult to imagine a functioning network supported by existing inefficient and insecure centralized solutions.

These are the problems that IoT programmers have yet to figure out. Demand for specialists in this field is only growing now, and in particular, demand for those who understand the vulnerabilities of hardware and software used by devices connected to the network. It is on these 5 pitfalls that the best programming minds are now beating.


The Internet of Things is an area that is currently new. How the industry will develop in the future is already predicted by tech evangelists. Security and centralization problems are still open, but with the introduction of 5G and AI, IoT developers will be able to cope with them and thus transfer the technology to a new level of development.
