* Title: EdgeCloudSim - EdgeServerManager
|
|
*
|
|
* Description:
|
|
* EdgeServerManager is responsible for creating and terminating
|
|
* the edge datacenters which operates the hosts and VMs.
|
|
* It also provides the list of VMs running on the hosts and
|
|
* the average utilization of all VMs.
|
|
*
|
|
* Please note that, EdgeCloudSim is built on top of CloudSim
|
|
* Therefore, all the computational units are handled by CloudSim
