Energy-Aware VM Initial Placement Strategy Based on BPSO in Cloud Computing

Algorithm 2

Random VM placement.

Input: VMList  Output:  ServerList

(2)  for  server  in  ServerList

(3)   if (server has enough resources to hold vm) then

(4)    if  then

(5)     server.setDisplacement;

(6)    end if

(7)    server.add(vm);

(8)    break;

(9)   end if
