Pantavisor Architecture

At a high level, Pantavisor is just in charge of two things: container orchestration and communication with the outside world.

Container Orchestration

The software that is running in a Pantavisor-enabled device at a certain moment is called a revision. A revision is composed by a BSP and a number of containers. Pantavisor is able to go from the current running revision to a new revision in a transactional manner.

Revisions, as well as other relevant data, are stored on-disk in the device to make them persistent.

Communication with the Outside World

Pantavisor-enabled devices need to communicate with the outside world to consume new updates, exchange metadata or send logs. Users can achieve this remotely as well as locally.
