Cross-VPC/Public Network Access Scenarios Supported by CloudTable Clusters
Scenario
- Connecting a CloudTable cluster to the peer cluster in another VPC in the same region
- Connecting a CloudTable cluster to the peer cluster in another region
- Accessing a CloudTable cluster from the public network
- Connecting a CloudTable cluster to an on-premises data center

Constraints and Limitations
Connecting a CloudTable cluster to the peer cluster in another VPC in the same region
ClickHouse
VPC peering connections: connect VPCs in a region in the same account or different accounts. For more information, see VPC Peering Connection Overview.
To enable the CloudTable cluster to access the peer cluster, you need to add a route for the cluster.
NOTE:To add a route, contact technical support.
Connecting a CloudTable cluster to the peer cluster in another region
ClickHouse
Cloud Connect: connects VPCs in different regions to quickly build cross-region networks. For more information, see What Is Cloud Connect?
To enable the CloudTable cluster to access the peer cluster, you need to add a route for the cluster.
NOTE:To add a route, contact technical support.
Accessing a CloudTable cluster from the public network
ClickHouse
Bind an ELB. Binding an EIP to the ELB provides public network access and load balancing capabilities for clusters. For more information, see What Is ELB?
The peer cluster cannot be accessed.
Connecting a CloudTable cluster to an on-premises data center
ClickHouse
- Direct Connect: Direct Connect provides a high-speed, low-latency, stable, and secure dedicated network connection between an on-premises data center and a cloud-based VPC. With Direct Connect, you can establish a large-scale hybrid cloud network. For more information, see What Is Direct Connect?
- Virtual Private Network (VPN): A VPN establishes a secure, encrypted communication tunnel between your on-premises data center and your VPC. For more information, see What Is Virtual Private Network?
To enable the CloudTable cluster to access the peer cluster, you need to add a route for the cluster.
NOTE:To add a route, contact technical support.
HBase public network access configuration:
- You can assign a public IP address to each HMaster and RegionServer node in the HBase cluster, bind the NAT gateway to the cluster's VPC, and set DNAT to full port mapping. For more information, see Configuring a NAT Gateway.
- Configure the host mapping on the client.
- Obtain the host names mapped to hosts and the private IP addresses of HMaster and RegionServer from technical support.
