Table 2 Experimental configuration
From: Maximizing the profits of cloud service providers via dynamic virtual resource renting approach
Type | Parameter | Value |
|---|---|---|
Service requesting layer | Number | 10,000 |
|  | Arrive rate | Poisson task at the rate of 80 per I λ Measured by small instance, the size is uniformly distributed |
|  | Task size | between 100 I λ to 300 I λ , that is 60 I λ to 160 I λ when measured by extra large instance |
Service providing layer | Rental approach | RS, RL, RXL, RR, FFP, DRAP |
Virtual resource supplying layer | Virtual machine | Small instance, large instance, xlarge instance with the same configuration as Amazon small, large, xlarge spot instance |
| Â | Â | Dataset 1: spot prices of Amazon small, large, xlarge instance from June 1, 2011 to June 30, 2011 in eastern United States. |
| Â | Price | The OS is Windows |
| Â | Â | Dataset 2: normally distributed prices. The mean and variance is equal to Dataset 1 |
SLA | r pay | $ 0.078 per unit size |
|  | φ | 0.8 |
| Â | Ï• | 1.1 |
| Â | r penlty | 0 |
Parameter of weak equilibrium operator | δ | 0.9 and 0.8, respectively, for dataset1 and dataset2 |
|  | ε | 0.01 and 0.05, respectively, for dataset1 and dataset2 |
