Do I Need to Bind an EIP to Each ECS in the VPCs Connected over a Cloud Connection? What Can I Do If the Hybrid Cloud Network Set Up Using Cloud Connect and Direct Connect Is Disconnected?
Do I Need to Bind an EIP to Each ECS in the VPCs Connected over a Cloud Connection? If the ECSs are used only within the VPCs, no EIPs are required.

ECS 3 Create an ECS in each VPC to verify network connectivity. ECS Name: Set it based on site requirements. In this example, the names are as follows: Region A: ECS-A Region B: ECS-B Region C: ECS-C Image: Set it as needed.

Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.
Quotas can limit the number of resources available to users, such as the maximum number of ECS or EVS disks that can be created. If the existing resource quota cannot meet your service requirements, you can apply for a higher quota. How Do I View My Quotas?

Buy an ECS in CN East-Shanghai1. For details, see Purchasing an ECS. Private IP address of the ECS in CN East-Shanghai1: 172.16.36.220 Buy an EIP and configure a NAT gateway. In CN-Hong Kong, buy an EIP and a public NAT gateway, and add a DNAT rule.
ECS In this example, two ECSs are deployed in VPCs in different regions. An ECS can be only associated with a security group in the same region as the ECS. Therefore, the two ECSs must be associated with different security groups.
Public services, such as Elastic Cloud Server (ECS), Elastic Volume Service (EVS), Object Storage Service (OBS), Virtual Private Cloud (VPC), Elastic IP (EIP), and Image Management Service (IMS), are shared within the same region.

To test network connectivity, you can ping an ECS in one VPC from an ECS in the other VPC. If network instances are in the same region, they can communicate with each other by default after they are loaded to one cloud connection. Parent topic: Inter-Region Bandwidths

To test network connectivity, you can ping an ECS in one VPC from an ECS in the other VPC. Constraints If network instances are in the same region, they can communicate with each other by default after they are loaded to one cloud connection.
A global EIP and its associated resource, such as an ECS or load balancer, have to be in the same region.
An ECS in a VPC subnet has an EIP bound. In this case, the ECS will use the EIP to access the Internet instead of the NAT gateway. Parent topic: Route Information
