An EC2-based VPN is essentially a custom VPN server that runs on an EC2 instance. By using a preconfigured AMI from the AWS Marketplace, the setup process becomes incredibly simple, even for those with limited technical knowledge. This approach gives you full control over the VPN configuration, while avoiding the pay-per-user costs common with AWS’s managed VPN solutions.

An EC2-based VPN setup is perfect for smaller needs, like securely accessing your AWS test environments or development instances, or even for personal browsing. With the preconfigured AMI, you don’t need to install or manually configure VPN software. Just a few straightforward steps and you’re ready to go. I cover each of these steps in my tutorial, where I also explain practical use cases for the VPN. You can easily add MFA and be even more secure

Key Benefits of EC2-Based VPN

-- Cost-Effective --
Using the AWS Free Tier, you can set up and operate a VPN at almost no cost, as long as you stick within Free Tier limits (750 hours per month). This setup avoids the per-hour costs that AWS’s managed VPN options charge, making it ideal for individual use, small projects, or hobbyist applications.

-- Flexibility and Control --
An EC2-based VPN allows you to adjust settings as you see fit. You have full access to the VPN instance and can customize it to match your specific needs, whether it’s adding users, adjusting encryption, or experimenting with different network configurations.

-- Simple Setup with Minimal Technical Knowledge --
Thanks to the preconfigured AMI from the AWS Marketplace, setting up an EC2 VPN is straightforward. The AMI simplifies the setup process, so even users with limited technical knowledge can quickly establish a secure VPN to their AWS environment.

-- Privacy for Browsing --
An EC2-based VPN allows for private, secure internet browsing from your home or other locations, giving you peace of mind for online privacy. This can be useful for bypassing network restrictions or for extra privacy while accessing sensitive resources.

-- Simple Multi-Factor Authentication (MFA) Integration --
You can easily enhance security by adding MFA to your setup. This extra layer of security helps ensure that only authorized users can access your VPN by requiring a one-time code in addition to a password. Using popular MFA tools and apps like Google Authenticator or Authy, you can set up MFA with minimal effort, providing robust protection against unauthorized access. This feature is ideal for users who want to secure their AWS environments further, especially when accessing sensitive resources remotely.

-- Flexible Remote Access for Testing --
This VPN setup enables you to connect remotely to test AWS resources across multiple regions. If you're running regional-specific tests or development environments in AWS, an EC2 VPN can provide quick access without requiring you to be physically present in each region.

-- Integration with AWS Ecosystem --
Since the VPN runs on EC2, it integrates well with other AWS services. You can combine the VPN setup with S3 storage, RDS databases, or even Lambda functions, making it easy to access your AWS resources as if they were part of your local network.

-- Extendable for Larger Projects --
As your needs grow, the VPN setup on EC2 can be scaled to support additional users, higher bandwidth, or multiple instances.

Comparison: EC2-Based VPN vs. AWS Managed VPN Services

AWS also offers two managed VPN options. Client VPN for individual client connections and Site-to-Site VPN for linking entire networks. These services provide easy-to-use solutions with high availability, though they come at a higher cost and can offer more than a single user or small project may need.

Summary

An EC2-based VPN offers a flexible, low-cost way to securely access AWS from anywhere, making it especially valuable for testing regional setups and experimenting with AWS services at no extra cost.
