How do you connect ECS instances together? How do you connect them to the Internet? Well, the key component in ECS networking is what we call the Virtual Private cloud or VPC.
Virtual Private Cloud (VPC)
VPCs are logically isolated networks established in Alibaba Cloud. You can customize the topology and IP addresses in a VPC. We recommend that the VPC network type is used if have high network security requirements.
For more information about VPC, see Virtual Private Cloud documentation.
