Another one to look at is vpncloud: https://github.com/dswd/vpncloud. It's written in Rust. I've used it in production for several years now.

What Hacker News says
11 sourcesAnother tool to look at is vpncloud (https://github.com/dswd/vpncloud). It also builds a mesh network over UDP. Key setup is a bit easier, static keys are only used for authentication. Encryption keys are dynamically generated and replaced on a schedule.
I combine it with an ansible script to push out the (minimal) configuration to end nodes.
In Tinc, a GPLv2 mesh routing VPNAnother tool worth looking at is vpncloud (https://github.com/dswd/vpncloud). I used to use tinc, but switched to vpncloud 2 years ago.
In my use case, I have a modest number of nodes. Although nodes learn of other nodes from each other, I use ansible to keep each node's config updated.
I use vpncloud (and previously, tinc) between docker hosts. So, you have to be careful about interface MTU's inside of docker, particularly if you use containers based on Alpine.

4 points · Open discussionI think one of the reasons is that people confuse physical servers with manual administration. As I said, I do not do manual administration. Nothing ever gets configured on any server by hand. All administration is through ansible.
I only have one ansible setup, and it can work both for virtualized servers and physical ones. No difference. The only difference is that virtualized servers need to be set up with terraform first, and physical ones need to be ordered first and their IPs entered into a configuration file (inventory).
Of course, I am also careful to avoid becoming dependent on many other cloud services. For example, I use VpnCloud (https://github.com/dswd/vpncloud) for communication between the servers. As a side benefit, this also gives me the flexibility to switch to any infrastructure provider at any time.

hat while virtualized offerings do have their uses, there is a (huge) gap between a $10/month hobby VPS and a company with exploding-growth B2C business. Most new businesses actually fall into that gap: you do not expect hockey-stick exponential growth in a profitable B2B SaaS. That's where you should question the usual default choice of "use AWS". I care about my COGS and my margins, so I look at this choice very carefully.

This implements a novel cryptosystem. Default to not trusting novel cryptosystems until you have sufficient reason to begin believing that they are trustworthy.
