The unit features the following AosEdge components:
- Aos Communication Manager (CM):
- communicates with cloud
- downloads and validates system update image and services, layers
- Aos Service Manager (SM):
- handle services file system layers
- handle services' life cycle
- Aos Update Manager (UM):
- applies updates for different system components
- Aos Identity and Access Manager (IAM):
- provides system identifiers
- mange system keys and certificates
- manage services API permissions
Components interactions
On the unit side, CM interacts with:
- IAM in order to get unit systemID and current Users. CM receives notification from IAM when Users changed. When it happens CM reconnects to Aos Cloud with new parameters.
- SM to manage services ana layers on the system
- UM to get the current FOTA version and trigger updates
On the cloud side, CM communicates with:
- Service Discovery – to get Getaway connection info
- Gateway – to handle main exchange protocol
- Services CDN – to download service images
