Microsoft announced the launch of a secure end-to-end IoT product that focuses on microcontroller-based devices. At the core of Azure Sphere is a new class of certified MCUs. MediaTek is producing the first set of these new MCUs (single-core ARM-A7 systems that run at 500MHz).
Interesring twist is that for the first time ever, Microsoft is launching and promoting a custom Linux kernel and distribution: the Azure Sphere OS. (Earlier they have had their own Linux version in internal use at Azure).
The Microsoft-secured Linux kernel used in the Azure Sphere IoT OS is shared under an OSS license so that silicon partners can rapidly enable new silicon innovations. The devices can be used also with services that run on any other cloud.
