[Retracted] Sustainable Technical Debt-Aware Computing Model for Virtual Machine Migration (TD4VM) in IaaS Cloud

Algorithm 3

Migrate.

Input: Current timestamp

Average of Current Utility group (cu_avg)

Average combination of Predicted Utilitygroup (T₁, T₂, T₃)

Migrate (t, cu_avg, T₁, T₂, T₃)

1. Initialize: mig= n+1

2. if (cu_avg ≤ T₃)

3.  No need to migrate

4. else if (cu_avg≤ T₂)

5.   mig= t+3

6. else if (cu_avg≤ T₁)

7.  mig= t+2

8. else

9.  mig= t+1

10. end if

11. if (mig ≤ n)

12.  ‘migrate at timestamp’ mig

13. end if
