 ## Overview
 
-SDV project is a cooperative project with Futurewei, which will provide the technology-consulting services to develop and promote the 100 percent open source SDV (Software Defined Vehicle) software stack with reference design, with native integration of Cloud-Edge service capability. The SDV software stack is based on open source Autoware/ROS2/DDS and Zenoh, where DDS/Zenoh form an E2E Vehicle-Edge-Cloud middleware layer for the SDV platform. Thru the integration with Futurewei’ s open source KubeEdge project, the SDV platform will leverage Cloud Native Ecosystem tools to provide management, monitoring and software LCM (Life-Cycle-Management) functions.
