> It's also my not-so-secret hope that a sophisticated enough version of SadServers could be used by tech companies (or for companies that carry on job interviews on their behalf) to automate or facilitate the Linux troubleshooting interview section. Yup, that's what I was afraid of.

I knew this is where it was headed :/

Based on your architecture diagram it looks like you're spinning up an instance per-user? As you're probably finding now, you will hit AWS limits quickly.

You might instead want to have a smaller pool of (larger) servers that you run co-resident VMs on with https://firecracker-microvm.github.io/. That will avoid account limits and also keep your AWS costs more predictable.

I'm assuming you're spinning up an EC2 instance for each lab. What do you think about using pre-built docker images for each challenge instead? that way they can spin up in just a couple of seconds. Might also be cheaper?

probably lxd would be better.

Can't get to the first problem because of HN hug but anyway there are fake ways to "solve" it like renaming the logfile (what they test for solved is provided).

Depends on how the broken program writes to the log.

If it does

    while true; do echo hello >> bad.log; done
Then renaming bad.log will not solve the challenge.
