I've taken out a VPS from Ionos (formerly 1and1). It has 1 vCore, 1 GB RAM, 10GB SSD, unlimited traffic, root access, and a choice of distros, including Debian, Ubuntu & CentOS. Plesk is also offered free, but, I've not used it.
All for the ridiculously cheap price of £1 (£1.20 incl. VAT) per month. At this price it would be rude not to test it, which is what I'm doing.
The spec is limited, but, I can think of hundreds of uses at this price point.
