In 2017, IoT devices outnumbered people in the world for the first time, with around 300,000 developers supporting IoT technology. In 2020, the IoT industry will need 1,400 times that amount, or 4.5 million developers to support global growth, when over 30 billion IoT connected devices are expected to be installed worldwide.
But what does it mean for developers today? What are the biggest IoT trends and how will they impact your work?
While there’s nothing completely new and shiny on the IoT horizon, plenty of improvements are being made. Here are five emerging trends to keep an eye on.
Python and Java will dominate.
If you want to ride the IoT wave, make sure you know the dominant programming languages, namely Java and Python. A 2017 IoT Developer Survey conducted by the Eclipse Foundation lists Java as the top programming language for IoT development, particularly for gateways and the cloud. Python has gained traction for data-intensive applications and works well with small devices.
Research is paving the way for the launch of 5G.
Looking toward the 2020 rollout, loads of research is being dedicated to 5G, including how the technology will be used, how companies will invest in infrastructure, and how network providers will maintain profitability. The speed of 5G provides an opportunity for more devices to constantly gather and interpret data, from wearable tech that tracks geolocation and biometrics, to home technology that monitors house temperature and lighting along with external weather reports, allowing for predictive actions.
Location, location, location.
Enterprises are continuing to adopt IoT for location-based services, with lighting and temperature control systems being a key use case. This means that formerly low-maintenance appliances like your thermostat or floor lamp will now require management and monitoring, including firmware and software updates.
Healthcare and retail top the list of IoT use cases.
Use cases for IoT are growing fast, and the healthcare and retail industries are expected to see greater adoption of the technology in the coming year. The healthcare IoT market alone is forecast to reach $117 billion by 2020. Encrypting data transmission will be a priority, particularly for healthcare IoT devices.
Security remains a top concern.
One of the most important concerns is the need for solving the security issues of IoT devices that power everyday technology. Experts cite the prolific implementation of unsecured IoT devices as well as the growing availability of DDoS-for-hire services as root causes for DDoS attacks, which increased 91 percent in 2017. Developers will need to be vigilant about product security, including requiring https, and adding credential changes for secure devices.
