Billing
MgC is available free of charge. You need to pay for migration resources you consume.
Server Migration
During server migrations from on-premises or other clouds, you are billed at standard rates for resources used in the migrations. For details, see SMS Billing.
Storage Migration
During object storage migrations, public APIs of Huawei Cloud and source cloud vendors are called, and additional fees are applied. For details, see OMS Billing.
Migration Clusters
You are billed at standards rates for migration clusters and additional resources used during migrations.
- Master, migration, and list nodes in migration clusters are all ECSs, and you pay for these ECSs. For details, see ECS Pay-per-Use Billing or ECS Price Calculator.
- If you migrate over the Internet, you need to pay for NAT gateways used by migration clusters. For details, see NAT Gateway Billing or NAT Gateway Price Calculator.
- If you choose to enable log collection, you need to pay Log Tank Service (LTS) for resources you consume. For details, see LTS Billing or LTS Price Calculator.
Cross-AZ Migration
During cross-AZ migrations of ECSs, you need to pay for ECS, Image Management Service (IMS), and Cloud Backup and Recovery (CBR) resources used during the migrations.
- CBR vaults
During a cross-AZ migration of ECSs, if no vault is configured for the source ECSs, MgC creates a vault 1.5 times the combined size of the source ECS disks to facilitate the migration. The vault will be automatically deleted after the migration is complete.
For more details on CBR pricing, see CBR Billing.
- Images
During a cross-AZ migration, full-ECS images are created for the source ECSs to facilitate the migration.
For more details on IMS pricing, see IMS Billing.
- Target ECSs
MgC cannot migrate source servers to existing ECSs. It creates pay-per-use ECSs as the target servers. After the service cutover is complete, you can change the billing mode of target ECSs from pay-per-use to yearly/monthly.
For the pricing details of pay-per-use ECSs, see Pay-per-Use Billing.
CAUTION:
- The prices listed in the documentation are estimates only. The actual prices may vary.
