What network types does a VPC have?

Hi there!

A VPC has four types of networks: Internal network, routed network, direct network, and external network.

Internal network: only raw VLANs are provided. IP address management is optional. No gateway is provided. This network has only Layer 2 and does not provide Layer 3 access. This network is used for internal use and cannot be routed to external networks.

Routing network: provides VLAN, IP address management, and Layer 3 gateway. For all routed networks in a VPC, routes between these routed networks are automatically established so that VMs on different routed networks can access each other.

Direct network: Provides the capability of directly connecting VMs to external networks. VMs deployed on this network can be assigned external IP addresses.

External network. The external network is the network plane that the gateway and route are not managed in the virtual data center solution. Provides the capability of directly connecting VMs to external networks. An external network is represented as an independent VLAN in the virtual data center solution. The virtual data center solution does not manage the IP address allocation in this VLAN.

I have a picture to help you understand.

The Virtual Private Cloud (VPC) service enables you to provision logically isolated, configurable, and manageable virtual networks for Elastic Cloud Servers (ECSs), improving the security of resources in the system and simplifying network deployment.

You can select an IP address segment, create multiple subnets, customize security groups, and configure route tables and gateways in your VPC. With a VPC,you can manage and configure internal networks and change network configurations flexibly and securely. You can also customize access rules and firewalls to control ECS access within a security group and across different security groups to enhance security of ECSs in the subnet.

In addition, you can create a Virtual Private Network (VPN) to connect your data center or private network to your VPC. With a VPN, you do not need to set up port forwarding using an external IP address.

Internal network : Only L2 VLAN is available, optionally supporting IP address management. Gateway is not provided. This network has only two layers and does not provide three-tier access capabilities. This kind of network is generally used for internal use and not for external routing

Routed network has flexible interoperability and multiple business functions. It can communicate with other routing networks or Internet in VPC through routing mode. Routed networks can also provide flexible IP, DNA T, ACL and VPN services to meet more business deployment needs. Before creating a routing network, you first need to apply for a router for VPC

external network : Provides the ability to connect virtual machines directly to external networks. VMs deployed to this network can be assigned to external IP addresses .

A VPC provides a secure and isolated network environment for a VDC.
The VPC allows you to customize virtual networks that serve as traditional networks,and it provides advanced networkservices (such as elastic IP addresses and routers) to meet service deployment requirements.
• Isolated environment: The VPC provides a secure and isolated network environment to meet network isolation requirements of differerent departments.
• Abundant services: The VPC provides router, elastic IP address, security group, ACL, VPN, and load balancer services.
• Flexible networking: The VPC supports multiple networking modes, such as direct networks, routed networks, and internal networks.
