A Virtual Private Cloud (VPC) is a logically isolated section of the LYNIO Cloud where you can launch resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of IP address ranges, creation of subnets, and configuration of route tables.
Understanding VPCs
When you create a VPC, you specify an IPv4 CIDR block (e.g., 10.0.0.0/16). This defines the total pool of IP addresses available for resources inside this VPC.
Creating a VPC
- Go to Networking > VPC Networks in the LYNIO Console.
- Click Create VPC.
- Provide a name and a CIDR block (e.g.,
10.10.0.0/16). - Click Create.
Configuring Subnets
Subnets allow you to partition your VPC into smaller, more manageable network segments. For example, you might create a public subnet for web servers (10.10.1.0/24) and a private subnet for databases (10.10.2.0/24).
Creating a Subnet
- Navigate to the details page of your VPC.
- Click on the Subnets tab.
- Click Add Subnet.
- Provide a name and a CIDR block that fits within your VPC's range.
- Click Save.
Dynamic Routing Gateways (DRG)
A Dynamic Routing Gateway (DRG) is used to connect multiple VPCs together. This allows for complex network topologies, including coupling VPCs across different LYNIO Cloud regions to create a seamless private global network.
- Go to Networking > DRGs.
- Click Create DRG and attach your VPCs to it to enable inter-VPC routing.
Internet Access (IGW & Floating IPs)
To allow resources in your VPC to access the internet (or be accessed from the internet):
- Outbound Traffic: Every Subnet/VPC uses an Internet Gateway (IGW) and an Edge router. Instances without a public IP can automatically route traffic to the public internet using a shared outbound Floating IP.
- Inbound Traffic: To make a specific instance publicly reachable, you must assign a Floating IP directly to it.
# Example routing check inside your instance
ping 8.8.8.8
If the ping succeeds, your internet routing is correctly configured.
