VPC Overview

The VPC (Virtual Private Cloud) functionality allows you to group your virtual machines in a completely isolated virtual private network, with internal Layer 2 communication, ideal for secure, segmented, and organized environments.

🌐 What is a VPC?

A VPC is a private virtual network where connected virtual machines share the same IP range and can communicate with each other directly, as if they were on the same local network.

• Machines receive private IPs via DHCP.
• All traffic between them is encapsulated in a private tunnel.
• VPCs do not communicate with each other by default.

Key Components

Supported Network Components

Component	Purpose	Description
Single VPC Network	Isolation and Organization	Create a single private network to group and isolate your virtual machines.
Route Table	Traffic Control	Defines internal routing between VMs and outbound traffic to the internet via gateway.
VPN Gateway	Secure Remote Access / NAT	Enables secure remote access via VPN and also acts as NAT Gateway for internet outbound traffic.
Per-VM Firewall	Security Control	Individual firewall rules applied directly to virtual machines.
Private IP Assignment	Private Addressing	Private IPs are automatically assigned via DHCP to each VM in the VPC.
