Hi guys I have some questions . I know the definition of these classes but I wanna know the exact difference between these classes in cloudsim in more practical way :
1- what is the difference between datacenter power class and data center non power class and data center class?
2- What is the difference between host power class and host class
3- How to reduce the migration time and would you please the migration types too?
Thanks
Hi Nasim,
For points (1) and (2), the only difference is that the Power classes (for data center and host) enables you to simulate power-aware data centers so that you can calculate the energy consumption per each host or per data center.
For (3), the migration time per virtual machine depends on two parameters which are the amount of memory used by the virtual machine and the available network bandwidth, so you can minimize the migration time per a single VM by having more network bandwidth available. Too many unnecessary migrations will degrade the overall performance.
how can i get the amount of memory used by the virtual machine in cloudsim
The difference is that power classes enable creating power-aware simulations, in the same way that network classes enable network-aware simulations.
However, if you want to build joint power- and network-aware simulations, try CloudSim Plus at http://cloudsimplus.org
