Nowadays, Internet of things software development is actually a minefield. The market needs high-quality, scalable, powerful, secure and user-friendly solutions. The Internet of things development team must re-evaluate its standard process to take all factors into account. What does it mean to reassess "everything" in the context of the Internet of things project?

Stumbleupon, developer of the Internet of things

Due to strong demand, there is fierce competition between Internet of things startups and development companies. This and the lack of generally accepted standards keep programmers looking for new practices and updated protocols. Only by taking every software problem of the Internet of things seriously can we achieve effective development.

1) operating system considerations

There are several technical factors that need to be carefully considered before starting Internet of things application development. First, the team must evaluate the Internet of things devices they will use. Unlike traditional desktops, Internet of things devices are much weaker and have relatively small memory capacity. This means that developers must choose the appropriate operating system. It should be not only suitable for the function of the equipment, but also meet its functional requirements.

The latest IoT developer survey shows that Linux is the first choice for Internet of things microcontrollers, restricted devices and gateways.

2) Select a gateway

When it comes to Internet of things gateways, they are the key to connecting all elements. Different devices can have different connection protocols: Bluetooth, Wi-Fi, serial port, Zigbee and various energy profiles. Gateways are located between connected devices, Internet of things sensors and clouds, so the entire Internet of things ecosystem depends on them.

Modern intelligent gateways provided by Dell, Intel, Nexcom, and other top vendors have some common mandatory features that make life easier for developers. You only need to choose one that meets the needs of the Internet of things application. You must consider interface and network specifications, power rating, memory capacity, development environment, and other parameters. By default, secure, private, and trusted communication between devices should be guaranteed.

3) choose the appropriate platform of the Internet of things

No sensible developer is willing to develop software from scratch. This is where the Internet of things platforms come in handy because they provide combinations of tools to bring your physical objects online. The platform market is huge and confusing, so make sure you choose wisely. Your preferred platform should provide:

Connect

Safety

Expandability

Easy to integrate

Usability

However, Internet of things developers should be aware that platforms for smart factories may not be suitable for connected cars or energy consumption solutions. Some companies even choose to use the actual data in the production process to build a real test platform to determine the appropriate platform.

4) re-emphasize security issues

Have you ever heard the IoT joke from Tim Kadlec? "S in the Internet of things stands for security." Yes, there is no "S" in the Internet of things. By definition, the Internet of things technology includes many connected devices, so hackers have multiple targets to scan for vulnerabilities. Not all the devices that make up the network are adequately tested for penetration. Here, the whole system is threatened.

By 2020, 25 per cent of companies will be involved in the Internet of things, while only 10 per cent of the IT security budget will be spent on protecting systems from these attacks, according to Gartner.

For developers of networking projects, the number of cyber attacks will continue to increase, and security is a huge challenge. The level of protection depends largely on how much security expertise the company is prepared to invest in the conceptual phase. To reduce the possibility of attacks and unauthorized access, use:

SSL/TLS encryption technology

Orphaned VLA

Independent enterprise VPN

Modern and newer antivirus

End user and machine-to-machine authentication

Vetted framework for Web development and design

Update the enterprise security architecture using traditional protection and control methods to meet the new challenges of today's Internet of things.

5) overall quality control

Quality assurance is another highlight of Internet of things software. Since the Internet of things devices are used not only for temperature control in the warehouse, but also for insulin pumps, the testing should be very thorough. Literally, any small problem can become fatal.

Make sure that security testing is included in the software development process from the beginning. To optimize the process, look for modules that do not need to be tested every release. Look for protocols that have been securely tested and remain the same in the next few versions.

In addition to security testing, usability and compatibility should also be ensured. It is also a good choice to provide technical support after the project is released.

6) user-friendly design

Consumer Internet of things applications should be design-driven and as simple as possible; no one wants to learn manuals to update smartwatches. User-friendly design is also important for industrial Internet of things startups because they should focus on data visualization and quick decision-making. Because every device, thing, and person is communicating with each other in the Internet of things workflow, there is close cooperation between Internet of things developers and designers to ensure that:

Secure but easy authentication

Seamless transition between equipment and system

Personalize the user experience and adjust the product according to behavior patterns

The unified environment of the whole Internet of things system

7) Cross-platform deployment

The Internet of things ecosystem includes devices with different architectures, protocols, and operating systems. All these variables should be combined and work seamlessly. As a result, the Internet Engineering Task Force (IETF), the Institute of Electrical and Electronic Engineers (IEEE), and other reputable organizations have proposed open standards and architecture models for cross-platform deployment. They are being updated all the time, and Internet of things services should take advantage of these best practices to ensure interconnected communications.

Conclusion:

Although the adoption of the Internet of things has increased in the past few years, there are still many problems to be solved in the software development of the Internet of things. Now, Internet of things companies and startups should pay attention to details they haven't considered.

Adopting accepted standards for Internet of things projects will enable us to partially address some of the development challenges. In particular, we can improve the security of Internet of things applications and their cross-platform deployment. However, because the Internet of things is a relatively new field, standards are still being developed. It will take a while for the Internet of things development community to generally recognize them.
