Creating VPCs and ECSs

Scenarios

This section describes how to create VPCs and ECSs. A third-party firewall needs to be installed on one of the ECSs.

Procedure

  1. Create three VPCs in region A.

    For details, see Creating a VPC.

    For details about VPC and subnet planning, see Table 10.

  2. Create three ECSs in region A.

    For details, see Overview.

    • For details about resource planning of ECS 1 and ECS 2, see Table 11.
    • Two NICs need to be installed on ECS 3. For details about resource planning of ECS 3, see Table 12.

      After ECS 3 is created, go to the ECS 3 details page. On the NICs tab, disable Source/Destination Check for the NIC eth1 to ensure that the traffic from eth1 is not blocked.

  3. Install a third-party firewall on ECS 3.
