/**
* A CloudSim Plus example which shows the Info-Aware placement
*
* Initially, we have a datacenter managing two hosts.
* After that two VMs, one that will be running a memory bound
* workload and the other one a network bound workload, will be
* allocated (using the VMAllocationPolicySimple), one in each of
* the hosts, and two cloudlets will be launched in each VM, one
* cloudlet with the double of the duration time in comparison with
* the another one. Finally, a third VM (with Memory Bound metadata)
* will be launched in the datacenter using the VmAllocationPolicyInfoAware,
* and it is expected that this VM will be allocated into the host
* with more memory available.
