Microvisor

Microvisor was a hypervisor-type middleware product for embedded Internet of Things devices developed initially by Twilio and, later, KORE Wireless. In August 2024, KORE Wireless canned the product and all further development of it. I was a member of the development team; not a core Microvisor engineer but the project’s technical writer and developer of both sample code and full applications based on the platform.

Only a small portion of Twilio’s Microvisor documentation was transferred to the KORE Wireless website, and those pages were never published. Microvisor documentation continues to be hosted on the Twilio website, however, but as it is surely only a matter of time before it is removed, I have begun to host it here, as a sample of my work as a technical author.

Though written by me, this documentation was entirely produced as an employee so it remains the property of KORE Wireless.

What is Microvisor?

Twilio Microvisor is a sophisticated new solution to the unique challenges posed to developers by Internet of Things (IoT) product design:

  • How you can ensure your devices will always be protected against an exponentially increasing number of attack vectors.

  • How you can ensure your devices will always be protected for their entire operational lives.

  • How you can keep device software up to date at sites where end-users may be unwilling or unable to perform this crucial task.

  • How you can diagnose issues with devices that may be located in a different country, in another continent or even in motion.
