577Performance Analysis for Large IaaS Clouds
In [6], Genaud et al. used simulations to evaluate scheduling strategies in cloud.
The authors primarily focused on minimizing the wait time of jobs and the monetary
cost of the rented resources. Our numeric–analytic models can complement such
studies. Goudarzi et al. [10] studied optimization problems for multitier cloud appli-
cations by taking into account requests with different CPU, memory, and network
resource requirements. Performance models developed in this paper can be extended
for such heterogeneous requests. Yigitbasi et al. [24] performed an experimental
analysis for the resource acquisition and release times in Amazon EC2. Our stochas-
tic models can complement these studies and analyze ...
