Package org.cloudbus.cloudsim.brokers

package org.cloudbus.cloudsim.brokers

Provides DatacenterBroker classes that act on behalf of a cloud customer, attending his/her requests for creation and destruction of Cloudlets and VMs, assigning such Cloudlets to specific VMs. These brokers can implement decision making algorithms to prioritize submission of Cloudlets to the cloud, to define how a VM is selected to run a given Cloudlets, etc.

The most basic implementation is the DatacenterBrokerSimple that uses a Round-robin algorithm to select a VM from a list to place a submitted Cloudlet, which is called a Cloudlet to VM mapping. Other class such as the DatacenterBrokerHeuristic allows setting a Heuristic to find an sub-optimal mapping.

Class	Description
DatacenterBroker	Represents a broker acting on behalf of a cloud customer.
DatacenterBrokerAbstract	An abstract class for implementing DatacenterBrokers.
DatacenterBrokerBestFit	A implementation of DatacenterBroker that uses a Best Fit mapping between submitted cloudlets and Vm's, trying to place a Cloudlet at the best suitable Vm which can be found (according to the required Cloudlet's PEs).
DatacenterBrokerFirstFit	A implementation of DatacenterBroker that uses a First Fit mapping between submitted cloudlets and Vm's, trying to place a Cloudlet at the first suitable Vm which can be found (according to the required Cloudlet's PEs).
DatacenterBrokerHeuristic	A simple implementation of DatacenterBroker that uses some heuristic to get a suboptimal mapping among submitted cloudlets and Vm's.
DatacenterBrokerSimple	A simple implementation of DatacenterBroker that try to host customer's VMs at the first Datacenter found.
