Exploration and Practices of Edge Computing Chapter 3 Cloud Managing Virtualized Devices Introduction to the Architecture of Pallas The previous article introduced how to build and install virtualized devices, but did not touch how to manage large-scale virtualized devices from the cloud. This article introduces the architecture of Pallas to achieve the above goal. Pallas is the second milestone of the project Asteroid after Ceres . In this release, the basic problems of cloud managing virtualized devices are solved: The device-cloud connection is narrow and unstable Large scale of devices Serious security concerns, often forbidding any open ports The main functions of the Pallas architecture are implemented by the device manager and the agent virtual machine. Its design key points are: Adopt MQTT protocol suitable for narrow-band, unstable network connections The device manager in the cloud adopts the design concept of typical Internet architecture, with mu
