Good, I'm a bit confused on the subject. I understand that the VPS is a physical machine that has been divided into virtual environments, charged a fixed fee and has no swap partition.
The cloud server has a special infrastructure (I do not know what this refers to), and it abstracts the physical hardware of the server (what exactly does this mean?), has a swap partition and is generally better scalable than the vps.
Among the doubts I have put in parentheses, that there are other differences between these 2 technologies, and if when reference is made to cloud computing, it would also apply to the case of vps.
I put the digitalocean case in many places out that call it vps server and other cloud server, is there any error in the interpretation?
