Resource and Cost Planning
| Category | Subcategory | Plan | Remarks |
|---|---|---|---|
| Source VPC | VPC name | vpc-DRSsrc | Specify a name that is easy to identify. |
| Region | EU-Dublin | For low network latency and quick resource access, select the region nearest to you. | |
| AZ | AZ2 | - | |
| Subnet CIDR | 10.0.0.0/24 | Select a subnet with sufficient network resources. | |
| Subnet name | subnet-drs01 | Specify a name that is easy to identify. | |
| Source RDS instance | RDS instance name | rds-mysql-src | Specify a name that is easy to identify. |
| Region | EU-Dublin | For low network latency and quick resource access, select the region nearest to you. | |
| DB engine version | MySQL 5.7 | - | |
| Instance type | Single | A single instance is used in this example. To improve service reliability, select a primary/standby instance. | |
| Storage type | Cloud SSD | - | |
| AZ | AZ2 | A single instance is used in this example. To improve service reliability, create a primary/standby RDS instance and then deploy them in different AZs. | |
| Instance class | General-purpose 4 vCPUs | 8 GB | - | |
| Source VPN | Gateway name | vpngw-src | Specify a name that is easy to identify. |
| Region | EU-Dublin | For low network latency and quick resource access, select the region nearest to you. | |
| VPC | vpc-DRSsrc | The VPC must be the same as the VPC of the source RDS instance. | |
| VPN connection name | vpn-src01 | Specify a name that is easy to identify. | |
| Local subnet | subnet-drs01 | The local subnet is the VPC subnet of the source RDS instance. | |
| Remote gateway | 123.60.251.207 | Peer VPN gateway. The value is the gateway address of the destination VPN. After the destination VPN is created, the gateway address is obtained. | |
| Remote subnet | 172.16.0.0/24 | Subnet of the peer VPN. The value is the subnet of the destination VPN, which is the subnet of the VPC where the destination DDM instance is deployed. | |
| Destination VPC | VPC name | vpc-DRStar | Specify a name that is easy to identify. |
| Region | EU-Dublin | For low network latency and quick resource access, select the region nearest to you. | |
| AZ | AZ1 | - | |
| Subnet CIDR | 172.16.0.0/24 | Select a subnet with sufficient network resources. | |
| Subnet name | subnet-drs02 | Specify a name that is easy to identify. | |
| Destination DDM instance | DDM instance name | ddm-drs-tar | Specify a name that is easy to identify. |
| AZ | AZ1 | You can select one or more AZs. Ensure that the destination DDM instance is deployed across different AZs to improve service reliability. | |
| Node class | General-enhanced 8 vCPUs | 16 GB | - | |
| Nodes | 1 | A single node cannot provide high availability. Ensure that the destination DDM instance has at least two nodes. | |
| RDS instance associated with the DDM instance | RDS instance name | rds-ddm01 | Specify a name that is easy to identify. |
| Region | EU-Dublin | For low network latency and quick resource access, select the region nearest to you. | |
| DB engine version | MySQL 5.7 | - | |
| Instance type | Single | A single instance is used in this example. To improve service reliability, select a primary/standby RDS instance. | |
| Storage type | Cloud SSD | - | |
| AZ | AZ1 | A single instance is used in this example. To improve service reliability, create a primary/standby RDS instance and then deploy them in different AZs. | |
| Instance class | General-purpose 4 vCPUs | 8 GB | - | |
| Destination VPN | Gateway name | vpngw-tar | Specify a name that is easy to identify. |
| Region | EU-Dublin | For low network latency and quick resource access, select the region nearest to you. | |
| VPC | vpc-DRStar | The value is the VPC of the destination DDM instance. | |
| VPN connection name | vpn-tar01 | Specify a name that is easy to identify. | |
| Local subnet | subnet-drs02 | The value is the VPC subnet of the destination DDM instance. | |
| Remote gateway | 123.60.236.84 | Peer VPN gateway. In this example, this parameter is set to the gateway address of the source VPN. After the source VPN is created, the gateway address is obtained. | |
| Remote subnet | 10.0.0.0/24 | Subnet of the peer VPN. The value is the subnet of the source VPN, which is the subnet of the VPC where the source RDS for MySQL instance is deployed. | |
| DRS migration task | Task name | DRS-MySQLToDDM | Specify a name that is easy to identify. |
| Source DB engine | MySQL | In this example, the source is an RDS for MySQL instance on Huawei Cloud. | |
| Destination DB engine | DDM | In this example, the destination is a DDM instance. | |
| Network type | VPN network | In this example, VPNs are used. |
