A Novel Deployment Method for Communication-Intensive Applications in Service Clouds

Algorithm 1

Online deployment.

Input:

𝑆: The set of services of an application

𝑉: The set of candidate cloud nodes

MAX: The biggest number the system can operate

(1)   begin

(2)  when  𝑉≠∅;

(3)  minCO = MAX;

(4)  for all 𝑣∈𝑉

(5)  Calculate CO(𝑠,𝑣,𝑆);

(6)  if  CO(𝑠,𝑣,𝑆) < minCO

(7)     minCO = CO(𝑠,𝑣,𝑆);

(8)     𝑣_min = 𝑣;

(9)  end if

(10) end for

(11) Deploy 𝑠 in 𝑣_min;

(12) end
