I would like to employ a VPN on my public AWS instance for security. I see that AWS offers several solutions for this but they all carry the usual EC2/hr costs which add up to quite a lot over a year based on my usage of 25 users.
Why would I need/want to use a "bundled" VPN solution from AWS as opposed to simply installing a copy of SoftEther or OpenVPN and configuring it on the server to use as I would any other physical server I was administering?
My goal is to install SoftEther on my AWS Windows server and avoid all of the managed costs associated with AWS Client VPN or the like.
Am I missing something that precludes me from approaching it this way?
