Also make sure you know how the pricing works. There's a specific configuration that enables 4 ARM CPUs, 24GB RAM, and 200GB disk space on the free tier.

Signed up with a region, always out of any free availabilities, locked out with no way to change regions, unless if I sign up with a different email address.

last time I checked, they required credit card, sort of "free trial" roulette

Especially if you can run your stack on their Ampere processors. 4 vCPU and 24GB RAM... for free.
