The traditional approach to IoT connectivity often involves outsourcing the operation of required infrastructure, leading to vendor lock-in and high costs. A microvisor-based approach offers flexibility and freedom to choose development environment, operating system, and programming language, allowing for future-proofing and reducing legacy product maintenance costs. This architecture enables reliable remote operations, such as firmware updates and secure live debugging, on Internet-connected devices by leveraging hardware separation within a microcontroller, providing an added layer of security and support for multiple operating systems and languages. By adopting a microvisor-based approach, IoT developers can build secure, reliable, and efficient applications that remain adaptable and future-proof over time.
