BMSs support secondary virtualization. The user-defined network enables communication between the VM network and the VPC, and provides functions similar to the VPC network for the VM network. The main application scenarios and benefits are as follows:
- BMSs can be provisioned in private clouds (such as XenServer and KVM).
- VMs provisioned on BMSs in the private cloud can communicate with the Internet.
- VMs provisioned on BMSs in the private cloud can communicate with ECSs in the VPC.
- The private cloud based on BMSs and Direct Connect can communicate with the private cloud of the on-premises data center.
