Determining a number of nodes required in a networked virtualization system based on increasing node density

A non-transitory computer readable medium having stored thereon a sequence of instructions which, when executed by a processor causes a set of acts, the set of acts comprising:

• determining an initial density metric comprising a number of virtual machines supported by nodes for use in a networked virtualization system, the initial density metric being based at least in part on a constraint on a resource available on the nodes;
• receiving information describing a projected number of virtual machines to be supported by the networked virtualization system at an end of an analysis period;
• determining a projected increase in density of virtual machines supported per node at the end of the analysis period;
• and
• determining a projected number of nodes required at the end of the analysis period based at least in part the initial density metric, and the projected increase in density of virtual machines supported per node.
