Is there a specific reason you're tied to Azure (or any of the other 'big' providers)? I do all my spin-up/spin-down testing at Digital Ocean, Vultr, or Hetzne

Is there a specific reason you're tied to Azure (or any of the other 'big' providers)? I do all my spin-up/spin-down testing at Digital Ocean, Vultr, or Hetzner ... even if I happen to forget something's up and running, it's never more than ~$5-10 in a month (and I get the billing statement every month, so I can quickly nix stuff if I did happen to forget about it)
