Relationship Between UGO and Other Services
VPC Endpoint Service
UGO uses a VPC endpoint service as a proxy to connect to the target database. In this way, you can access your target database securely.
When you create a migration project, in addition to the UGO FullAccess permission, you need the VPC Endpoint Administrator or Tenant Administrator permission. A VPC endpoint service is automatically created and deleted by UGO when you create or delete a migration project.
The VPC endpoint service is free. UGO adds a whitelist to control permissions of the VPC endpoint service to ensure secure access to the target database. You can also view the VPC endpoint service of the target database on the VPC Endpoint console. To ensure that UGO functions are available, do not delete the VPC endpoint service of the target database before its migration project is complete.
Data Replication Service (DRS)
UGO migrates heterogeneous database schemas, such as tables, views, and stored procedures, to the cloud, resolving the incompatibility problem of database syntax conversion.
DRS supports database data synchronization in milliseconds. It supports data transmission and migration between homogeneous and heterogeneous databases, simplifying data transmission between databases and reducing data transmission costs.
You can use UGO and DRS to migrate heterogeneous databases with complex stored procedures and functions to Huawei Cloud.
Identity and Access Management (IAM)
Identity and Access Management (IAM) manages permissions for UGO.
Only users with the UGO administrator permissions can use UGO. To obtain UGO administrator permissions, contact a use with the security administrator permissions or apply for a user with UGO administrator permissions.
For more information about IAM, see Identity and Access Management User Guide.
Cloud Trace Service (CTS)
Cloud Trace Service (CTS) records operations related to UGO, facilitating additional queries, audits, and retrievals.
For more information about CTS, see Cloud Trace Service User Guide.
