Amazon VPC vs OpenVPN: What are the differences?
What is Amazon VPC? Provision a logically isolated section of the AWS Cloud and launch AWS resources in a virtual network that you define. You have complete control over your virtual networking environment, including selection of your own IP address range, creation of subnets, and configuration of route tables and network gateways. You can easily customize the network configuration for your Amazon VPC.
What is OpenVPN? A Business VPN to Access Network Resources Securely. It provides flexible VPN solutions to secure your data communications, whether it's for Internet privacy, remote access for employees, securing IoT, or for networking Cloud data centers. Our VPN Server software solution can be deployed on-premises using standard servers or virtual appliances, or on the cloud.
Amazon VPC and OpenVPN can be primarily classified as "Virtual Private Cloud" tools.
According to the StackShare community, Amazon VPC has a broader approval, being mentioned in 300 company stacks & 79 developers stacks; compared to OpenVPN, which is listed in 15 company stacks and 3 developer stacks.

VPC launched in mid 2009 as a companion product to the existing EC2 offering, though it quickly became considered to be EC2 2.0, as it remedied many of the commonly accepted EC2 downfalls. At face value, the migration didn’t seem conceptually difficult, as VPC was just another software abstraction on top of the same hardware, yet it was much more complex, with a few main issues:
- You cannot migrate a running instance.
- AWS offers no migration plan.
- EC2 and VPC do not share security groups.
This last point lingered in our heads as we tried to come up with a solution. What would it take to make EC2 and VPC talk to each other as if the security groups could negotiate? It seemed insurmountable: we had thousands of running instances in EC2 and we could not take any downtime. We were looking for a solution that would allow us to migrate at our own pace, moving partial and full tiers as needed, with secure communication between both sides.
So, we created Neti, a dynamic iptables-based firewall manipulation daemon, written in Python, and backed by Zookeeper.
Our architecture is running in Amazon VPC. That's actually what we started with and we're still very happy with. We’re pretty much tied into the entire platform.
The DB and some servers on a separate sub-net in the VPC. This ensures access to these servers are denied from any other machine than the VPC.
With VCP, you can secure and segment your nodes.
It is easy to manage, flexible, and gives great control over your virtual infrastructure.
