Connecting Your On-Premises Data Center to the Cloud

Scenarios

Establish network connectivity using Direct Connect if cloud servers in your VPC need to communicate with your on-premises data center.

Restrictions and Limitations

100.64.0.0/10 is used in VPCs. Plan the CIDR blocks used in your on-premises data center and on the cloud in advance to ensure that IP addresses of the cloud gateway and your on-premises gateway do not overlap.

Procedure

  1. Collect the information listed in Table 1.
