    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.
