I still marvel at just how good Tailscale is. I'm a minor user really but I have two sites that I use tailscale to access: a couple of on-prem servers and my AWS production setup.
I can literally work from anywhere - had an issue over the weekend where I was trying to deploy an ECS container but the local wifi was so slow that the deploy kept timing out.
I simply SSH'd over to my on-prem development machine, did a git pull of the latest code and did the deploy from there. All while remaining secure with no open ports at all on my on-prem system and none in AWS. Can even do testing against the production Aurora database without any open ports on it, simply run a tailscale agent in AWS on a nano sized EC2.
Got another developer you need to give access to your network to? Tailscale makes that trivial (as it does revoking them).
Yeah, for that deployment I could just make a GitHub action or something and avoid the perils of terrible internet, but for this I like to do it manually and Tailscale lets me do just that.
