Ask HN: Where best to host multiple side projects?

I have accumulated a few side projects over the years (around 10) and would like to move them all to one of the more "modern" web hosting platforms, but without breaking the bank (was hoping for under $100 pm).

Which hosts allow you to run multiple domains, all from a single billable account? Is it possible to have all the projects kept completely separate?

In my particular case I need Linux, SSH, git, cron job access etc
