Over-the-Air Software Updates Without Downtime or Service Disruption Using Unikernels

Explore a 37-minute conference talk on implementing over-the-air (OTA) software updates without downtime or service disruption. Delve into the world of unikernels and their benefits for IoT products, focusing on security, performance, and operational aspects. Learn about IncludeOS, a unikernel operating system, and its Live Update functionality. Discover how to perform atomic updates on devices using Mender.io. Gain insights into the IoT landscape, manual update challenges, and the importance of user-initiated updates. Examine the open-source Apache-licensed project and compare various operating system approaches, including virtualization, containers, and virtual machines. Understand the advantages of unikernels, such as smaller size, single-threaded operation, and improved security through the absence of shells and daemons. Investigate the Acorn project's components, including client libraries, demo applications, and dashboards. Conclude with an overview of supported architectures and callback methods for implementing OTA updates in IoT devices.
