SDWAN module is worked as a software-defined router which can be used to define the rules when connecting to the external internet. It is implemented as CNF instead of VNF for better performance and effective deployment, and leverage OpenWRT (an open-source project based on Linux, and used on embedded devices to route network traffic) and mwan3 package (for wan interfaces management) to implement its functionalities, detail information can be found at: SDWAN Module Design

Cloud Storage:

Cloud Storage which used by BPA Rest Agent to provide storage service for image objects with binary, container and operating system. There are 2 solutions, MinIO and GridFS, with the consideration of Cloud native and Data reliability, we propose to use MinIO, which is CNCF project for object storage and compatible with Amazon S3 API, and provide language plugins for client application, it is also easy to deploy in Kubernetes and flexible scale-out. MinIO also provide storage service for HTTP Server. Since MinIO need export volume in bootstrap, local-storage is a simple solution but lack of reliability for the data safety, we will switch to reliability volume provided by Ceph CSI RBD in next release.
