In the era of active business migration to the cloud, corporate data security becomes a top priority. One of the key solutions for protecting network interactions between services, offices, and remote employees is the Virtual Private Cloud (VPC). It allows building an isolated, encrypted, and manageable network infrastructure on top of public clouds.
In this article, we will discuss why a virtual private cloud is needed, what options exist, how to deploy a VPC in the cloud, and how to ensure maximum protection of your infrastructure.
Why use a virtual private cloud?
A virtual private cloud enables the creation of a secure communication channel between different nodes — servers, workstations, cloud environments, and user devices — even if they are located in different countries or cloud providers.
Main tasks solved by VPC in the cloud:
- Infrastructure isolation — resources are not accessible directly from the public network.
- Traffic encryption — protection against interception and data analysis.
- Secure employee access — remote work without risking internal data.
- Connection between different clouds — building hybrid or multi-cloud architectures.
Types of VPC you can use in the cloud
Depending on goals and architecture, different types of VPC can be used:
| VPC Type | Description | Use Case |
|---|---|---|
| Site-to-Site VPC | Permanent channel between two or more networks (e.g., office ↔ cloud) | Connecting offices, linking to VPC |
| Client-to-Site VPC | Individual devices connect to the cloud network | Remote work, home access |
| Cloud-native VPC | VPC functions built into the cloud provider (e.g., Google Cloud VPN) | Integration within cloud platform |
| OpenVPN / WireGuard | Self-hosted setup on a cloud server | Flexibility and control, high-level encryption |
How to deploy VPC in Serverspace cloud
The Serverspace platform allows you to deploy a VPC within minutes. Below is an example of setting up OpenVPN.
Step 1: Create a cloud server
- In the Serverspace control panel, select OS (e.g., Ubuntu 22.04)
- Specify configuration — from 1 CPU, 1 GB RAM
- Enable public IP
Step 2: Install OpenVPN
Connect to the server via SSH and run:
Follow the script instructions: it will create CA, server and client keys, and configure the setup.
Step 3: Configure access
- Allow UDP port 1194 in the firewall
- Download the client .ovpn file
- Connect from PC, smartphone, or router
Security recommendations
To make your VPC as secure as possible:
- Use modern protocols — OpenVPN with AES or WireGuard
- Restrict access by IP addresses
- Apply two-factor authentication (via scripts or third-party tools)
- Enable connection attempt logging
- Regularly remove unused keys
- Keep the server and OpenVPN updated to the latest versions
Examples of virtual private network usage
- Application protection — access to 1C or CRM web interfaces only via VPC
- Interregional IT network — company branches connected to a unified cloud infrastructure
- Dev/test environment isolation — access to staging servers only inside VPC
Conclusion
The virtual private cloud is an integral part of modern cloud architecture. It allows you to protect data, restrict access, and link disparate components into a unified secure system. Thanks to Serverspace, you can deploy your own VPC in just minutes, gaining full control over configuration and security.
FAQ
- Can I connect from a phone? Yes. OpenVPN and WireGuard clients are supported on iOS and Android.
- Is it safe to use VPC in the cloud? Yes, if basic security measures are followed: encryption, firewall, access control.
- How long does it take to set up a VPC? From 10 to 30 minutes depending on experience and number of clients.
- How much does it cost? You pay only for the cloud server. No licensing fees for VPC.
