When an internet of things (IoT) sensor or microcontroller is embedded into a physical object, that piece of hardware is effectively converted into an internet-ready computer, capable of connecting to a local network and running code-based applications. Just as smartphones and tablets have been normalized as "computers" in their own right, so are these embedded devices, from home appliances (e.g., smart fridges and thermostats) to enterprise assets (e.g., smart factory equipment). IoT operating systems allow developers and business teams to engage with these embedded objects, program their functionalities, and track the data they produce as part of IoT applications, with processing capabilities at the scale necessary for continuous, stable performance. Just as standard operating systems like Linux, iOS, and Windows help users perform functions and manage software on a computer, IoT operating systems allow users to perform computer functions within connected devices.
IoT operating systems may be referred to in a number of ways, including IoT OS, real-time operating systems (RTOS), and embedded operating systems (embedded OS). Many of the platforms in this category are offered as open source, allowing any user to review the code and modify it as needed for the IoT projects. To realize the full benefits of smart technology, embedded systems require an IoT OS for processing applications, storing data, and staying protected against unwanted access. Due to the nature of the IoT space, vendors constantly update their products to be in line with the latest capabilities, security threats, and hardware integrations. Developers can manage these software and driver updates along with other critical information on a device’s RTOS, manually executing software or reconfiguring device settings whenever necessary. Users can also leverage these platforms to schedule specific workflows on individual devices, such as automated processes or the powering down of certain features as needed to save battery power.
Key Benefits of IoT Operating Systems
Increasingly, businesses across the spectrum of industries are making IoT strategies a priority. Connected devices and objects can optimize operations as well as the customer experience in ways not previously possible. With that being said, these initiatives are no small undertaking, and may require a substantial investment of resources to embed physical assets with the necessary hardware, design applications on IoT platforms or development tools, and oversee device processes once a project is deployed. IoT operating systems are an essential step in this journey, giving developers access and control over individual devices and helping to execute the intended applications for each asset or system of devices. If your business is considering an IoT project to connect distributed objects, enable new capabilities, and uncover actionable data across the operation, an IoT OS is a critical tool for completing this digital transformation.
A core capability of an IoT OS is the rapid execution of a task in response to triggers or specific data that is generated by the embedded sensor or shared from another device on the network. These software platforms are often referred to as real-time operating systems or RTOS because of this reliable, real-time processing with minimal buffer delays. These platforms are built for low resource utilization, with constraints related to size, memory, power, and processing capacity. By investing in the right IoT OS, you can set up your IoT devices for success in whatever scenario you deploy them. Because of the open-source nature of many of these tools, your team can tweak these systems per the demands of your particular IoT framework and assets. The active development community surrounding IoT also empowers users to find custom code that is created by others to help with a wide variety of use cases, as well as sharing of your own custom code across the community. IoT operating systems help users bridge the gap between embedding physical objects with intelligent sensors and bringing them to life in fully realized sensor networks.
The IoT products in this category are configured and managed with source code, and are compatible with different programming languages (for example, C and C++), depending on the solution. As such, experienced developers are the ideal users for these products. A number of IoT OS solutions are open source, allowing developers to view the complete source code and modify it as necessary for its applications within their business, whether for implementing security measures or developing unique data and process flows. Users may be able to find, utilize, and share custom code on vendor-supported community forums. Wherever an IoT project is deployed, it serves to benefit employees and clients across the operation, while delivering actionable insights that can impact overall business strategy and processes. With that being said, a company’s developers—whether in dedicated IoT roles or general development teams—will be most directly engaging with the IoT OS products that are deployed across connected fleets of devices.
Closed-source or open-source RTOS are made available with various features and specifications that are important for businesses to consider. These may include connectivity, processing, memory, and security features, as well as limitations. The following are some primary features to consider during research.
Integrated development environment (IDE) — IoT operating systems may provide an integrated development environment or IDE on which developers can modify source code and build custom code for deploying their OS as needed across connected devices. These interfaces may be available online or as downloadable software tools. Depending on the solution, it will offer support for one or more modern programming languages (C++, Rust, Python, etc.). In some cases, these solutions will allow users to export projects into other IDEs for continued development.
Device and component support — For an IoT OS to work in a programmer’s intended environment, it must offer compatibility with the various hardware assets in the development stack as well as the connected device architecture. These can include development boards, sensors, and microcontrollers, as well as the various embedded architectures that may be at use in electronic products. The solutions in this category typically offer hardware support for a range of common assets being used in IoT projects; however, specific capabilities vary from platform to platform.
Developer community — A number of the IoT OS vendors featured in this category provide access to an online community where users can exchange custom source code and discuss any experience, issues, or advice related to these applications. Vendors themselves may contribute to the discussions in these developer communities, with insights into user feedback, assistance with troubleshooting, or announcements about new product features or versions. These communities are especially common for those solutions that are free and open source. In situations where an online community is not available, these vendors may offer regularly updated user guides and product documentation to provide assistance with using their IoT OS solutions.
