Hello, everyone!

What are the network types of VPCs? What are the functions and features?

I am expressing my gratitude in advance!

Hello, friend!

The VPC network type includes Internal network, routed network, direct network, and external network.

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

Routed network: Provides VLAN, IP address management, and Layer 3 gateway. Routes between all routed networks in a VPC are automatically established so that VMs in different routed networks can access each other.

Direct network: Allows VMs to be directly connected to the external network. VMs deployed on this network can be assigned external IP addresses. 

External network: An external network refers to a network plane on which gateways and routes are not managed in the VDC solution. Allows VMs to be directly connected to external networks. The external network is represented as an independent VLAN in the VDC solution. The VDC solution does not manage IP address allocation in this VLAN.

Internal

Hope this helps!

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.


TYPES OF VPC Network (source)


Internal network:
only bare VLANs are provided, and IP address management is optional. No
gateway is provided. This network has only two layers and does not
provide the ability to access Layer 3. Such networks are generally used
internally and do not allow networks with external routing.
Routing network: Provides
VLAN, IP address management, and Layer 3 gateway. For all routing
networks under a VPC, the routes between these routing networks are
automatically opened, so that virtual machines under different routing
networks can access each other.
Direct Connected Network: Provides
the ability to directly connect virtual machines to external networks.
VMs deployed to this network can be assigned to external IP addresses.
External network. The
so-called external network is the network plane that the gateway and
routing are not managed in the virtual data center solution. Provides
the ability to directly connect virtual machines to external networks.
The external network appears as a separate VLAN in the virtual data
center scenario, and the virtual data center solution does not manage
the IP address allocation on this VLAN.
