Uses of VmAllocationPolicy in org.cloudsimplus.allocationpolicies

Classes in org.cloudsimplus.allocationpolicies that implement VmAllocationPolicy

Modifier and Type	Class	Description
class	VmAllocationPolicyAbstract	An abstract class that represents the policy used by a Datacenter to choose a Host to place or migrate a given Vm.
class	VmAllocationPolicyBatchPlacementUnderloadedHosts	Allocates one different underloaded Host for each submitted VM from a List (in batch), if DatacenterBroker.isBatchVmCreation() is true, so that the broker sends a List of VMs to be created in a single event (instead of sending a new event for each VM).
class	VmAllocationPolicyBestFit	A Best Fit VmAllocationPolicy implementation that chooses, as the host for a VM, the one with the highest number of PEs in use, which has enough free PEs for a VM.
class	VmAllocationPolicyFirstFit	A First Fit VM allocation policy which finds the first Host having enough resources to place a given VM.
class	VmAllocationPolicyRandom	A VM allocation policy which finds a random Host having suitable resources to place a given VM.
class	VmAllocationPolicyRoundRobin	A Round-Robin VM allocation policy which finds the next Host having suitable resources to place a given VM in a circular way.
class	VmAllocationPolicySimple	A VmAllocationPolicy implementation that chooses, as the host for a VM, that one with the fewest PEs in use.
