Article 2: Shared Provider Public Network – Integrating with VPC and Floating IPs
Overview
Our cloud environment uses a shared provider public network to deliver external connectivity for your virtual machines. This network works seamlessly with your private Virtual Private Cloud (VPC) and floating IP system to ensure secure and flexible access.
How It Works
-
Private VPCs:
Each enterprise project is allocated a dedicated /24 subnet from the 10.10.0.0/16 range. These private networks isolate your internal resources for security and performance. -
Floating IPs:
To expose resources on your VPC to the public internet, you can assign a floating IP. This mapping connects a public IP address from the shared provider network to an instance within your private VPC. -
Provider Public Network:
The shared public network is maintained by Valex Cloud and serves as the gateway for all outbound and inbound internet traffic. It provides robust routing, high availability, and advanced security controls.
Integration Steps
- Provision Your VPC:
Upon project setup, your enterprise is assigned a private /24 subnet. Configure your internal network settings as needed. - Deploy Your Instances:
Launch instances within your VPC. By default, these instances are isolated from the public internet. - Assign Floating IPs:
For any instance that requires external access, request a floating IP via the cloud panel. The system automatically maps the floating IP from the shared provider network to your instance. - Manage Connectivity:
Monitor network traffic and adjust firewall or security group settings to control access to your resources.
Best Practices
- Separation of Traffic:
Use VPCs to segment internal workloads while managing public access through controlled floating IP assignments. - Security First:
Apply strict security group policies to regulate both inbound and outbound traffic for instances with floating IPs. - Documentation:
Keep detailed records of your VPC configurations and floating IP assignments to streamline troubleshooting and scaling.
