Conclusion

This VPN deployment script should provide a good foundation to setting up your own VPN instead of relying on a paid service. Although speed is dependant on the VM resources, it will still provide you with enough bandwidth to safely navigate the web. Feel free to make adjustments to your VM resources to see if it helps address the speed issues. I kept things to the free tier so that I don’t need to worry about costs.
