To allow VPN to access the migration resource group network segment, perform the following operations: Log in to the VPN console. In the navigation pane on the left, choose Virtual Private Network > VPN Gateways.
You have purchased and configured a VPN which connects to at least one VPC on the cloud. For how to enable and configure a VPN, see Configuring S2C Classic VPN to Connect an On-premises Data Center to a VPC.
Using a VPC Peering Connection to Enable Network Communications for the Same Region but Different Tenants Before configuring a real-time synchronization task, ensure that the source and destination databases can communicate with the real-time compute resource group that you want to
For details about how to buy and configure a VPN, see Configuring S2C Enterprise Edition VPN to Connect an On-premises Data Center to a VPC.
For example, if the destination database is far away from DataArts Migration (for example, the database is deployed outside the Chinese mainland and is connected to DataArts Migration in the Chinese mainland through a VPN), the RTT is much more than 2 ms, resulting in a migration
If they communicate through a VPN, NAT, or Direct Connect, the network bandwidth is subject to the VPN, NAT, or Direct Connect bandwidth. Destination write performance It depends on the performance of the data source at the destination.
If the Elasticsearch server is deployed on an on-premises data center or a third-party cloud, ensure that Elasticsearch can be accessed from the Internet through an EIP, or a VPN or Direct Connect connection has been created between the on-premises data center and Huawei Cloud.
Tenants can also use the VPN to migrate data from the on-premises data center to cloud services to ensure migration security. CDM works in push-pull mode. CDM pulls data from the migration source and pushes the data to the migration destination.
If the MySQL database is deployed on an on-premises data center or a third-party cloud, ensure that an IP address that can be accessed from the public network has been configured for the MySQL database, or the VPN or Direct Connect between the on-premises data center and the cloud
If the Oracle database is deployed on an on-premises data center or a third-party cloud, ensure that an IP address that can be accessed from the public network has been configured for the Oracle database, or the VPN or Direct Connect between the on-premises data center and Huawei
If the MySQL database is deployed on an on-premises data center or a third-party cloud, ensure that an IP address that can be accessed from the public network has been configured for the MySQL database, or the VPN or Direct Connect between the on-premises data center and the cloud
Establish a VPN between the on-premises data center and the VPC where the service resides. Leverage Network Address Translation (NAT) or port forwarding to access the network in proxy mode. The following describes how to use the port forwarding tool to access intranet data.
If the Oracle database is deployed on an on-premises data center or a third-party cloud, ensure that an IP address that can be accessed from the public network has been configured for the Oracle database, or the VPN or Direct Connect between the on-premises data center and Huawei
