Microsoft Azure Sphere microcontroller and associated cloud service are available

Azure Sphere, the service designed to better secure connected devices, is available this Monday. Microsoft had introduced Azure Sphere, based on a Linux operating system developed by the brand for microcontrollers, in 2018. This technology is the result of a research project from Microsoft, entitled “Project Sopris”.

“The IoT is in the experimental stage. Each company performs at least one experiment. But security keeps them from really scaling up, ”said Galen Hunt, Microsoft engineer and general manager of Azure Sphere.

Azure Sphere consists of Microsoft certified microcontrollers – single chip computers with processors, storage, memory and IoT capabilities – combined with the Linux based operating system and Azure Sphere cloud security service. The security service provides information on authentication, threat response, and device and application failures.

Consumer equipment and industrial equipment

The MediaTek MT3620, the first Sphere chip, includes an embedded security subsystem that Microsoft has called “Pluto”. Microsoft announced last year that it would work with NXP on another “Azure Sphere” certified chip, my i.MX 8, which will be adapted to artificial intelligence, and to richer graphics and user interface experiences. . Microsoft is also working with Qualcomm on the first Azure Sphere certified cellular chip – which will provide secure connectivity.

Microsoft officials have said that customers who previewed Azure Sphere have used it to design and produce consumer devices and industrial equipment. Azure Sphere certified MediaTek MT3620 chips are also used in “security modules” to securely connect and protect critical equipment, officials said.

The guard module is a device the size of a deck of cards built around a Sphere Azure chip, Microsoft officials said. Customers interested in connecting existing devices can connect via the guard module to connect it securely to the cloud. Microsoft’s Azure data center team used Azure Sphere and the guard modules in this way internally during the preview, officials said.
