At the heart of Azure Sphere is a customised Linux kernel.
The solution has three components:
- Azure Sphere certified microcontrollers, which combine both real-time and application processors with built-in security technology and connectivity. Custom silicon secures the MCU and the device it powers.
- Azure Sphere OS: Unlike the real-time operating systems used today, this offer multiple layers of security. It used security innovations developed for Windows and a custom Linux kernel.
- Azure Sphere Security Service: This turnkey, cloud service that guards every Azure Sphere device and brokers trust for device-to-device and device-to-cloud communication through certificate-based authentication.
