Hello, friend!
In HUAWEI CLOUD Stack scenarios:
ManageOne SC: ManageOne SC provides service catalogs for all services in the cloud data center solution and operation functions such as user and project management. Creates basic DR resources, including creating tenants' DR VMs and DR VPCs, and applying for and creating DR administrator roles.
IaaS+ cloud services: include basic computing, storage, and network services, such as ECS, EVS, and VPC. They are mandatory components of the cloud data center solution. The console of each cloud service is independently deployed and registered with ManageOne ServiceCenter and the public framework to implement service redirection and unified management. The basic computing, storage, and network resources required for applying for ECS DR are independently provided by each cloud service. Create DR placeholder ECSs, DR VPCs, and network services, and apply for and create DR administrator roles.
CSDR Console: CSDR Console is installed in the public framework and provides tenants with pages for adding, deleting, modifying, and querying CSDR instances and resource management. Provides DR test and clearance operations.
BCManager provides an operation interface for DR administrators to perform planned migration, reprotection, and failover of protected groups.
Hope this helps!
