AosCore

Introduction

AosCore is the on-Unit runtime that manages containerized services, handles over-the-air deployments, secures the Unit through certificate-based identity, and monitors resource usage. It runs on each AosEdge Unit at the edge and communicates with AosCloud over a WebSocket-based JSON protocol.
