Note you'll need a static IPv4[^1] address for reliable hosting[^2]. If you're behind Network Address Translation (NAT) you'll need to set up port forwarding for every service you want to run.

With no services 10GiB of disk space and 1GiB of RAM is plenty, though you may want to enable swap if you have low memory.

With all services enabled and fairly populated databases 40GiB of disk space and 2GiB of RAM is appropriate.
