description: >
Represents a real or virtual machine or ‘server’. Informations specified on the Compute
node will be used to find the machine that fits the given requirements in the cloud
available machines. If no sizing informations are specified the cloud’s provider default
machine will be used. It is strongly recommended to specify the required cpus and memory
at least.
