Package org.cloudbus.cloudsim.resources

Provides classes that represent different physical and logical Resource used by simulation objects such as Hosts and VMs.

There are different interfaces that enable the existence of resources with different features such as if the capacity of the resource can be changed after defined, if the resource can be managed (meaning that some amount of it can be allocated or freed in runtime), etc.

The most basic resources are HarddriveStorage, Ram, Bandwidth, Pe and File.

Interface Summary

Interface	Description
FileStorage	An interface which defines the desired functionality of a storage system in a Data Cloud that performs operations on a file system, such as file inclusion, exclusion and renaming.
Pe	A interface to be implemented by each class that provides the basic features of a virtual or physical Processing Element (PE) of a PM or VM.
Resource	An interface to represent a physical or virtual resource (like RAM, CPU or Bandwidth) that doesn't provide direct features to change allocated amount of resource.
ResourceCapacity	An interface to allow getting the capacity of a given resource.
Resourceful	An interface to be implemented by a machine such as a Host or Vm, that provides a polymorphic way to access a given resource like Ram, Bandwidth, Storage or Pe from a List containing such different resources.
ResourceManageable	An interface to represent a physical or virtual resource (like RAM, CPU or Bandwidth) with features to manage resource capacity and allocation.

Class Summary

Class	Description
Bandwidth	Represents the Bandwidth (BW) capacity of a PM or VM in Megabits/s.
DatacenterStorage	Implements the storage logic for a Datacenter.
File	A class for representing a physical file in a DataCloud environment
FileAttribute	Stores related information regarding to a File entity.
HarddriveStorage	An implementation of a Hard Drive (HD) storage device.
PeSimple	Pe (Processing Element) class represents a CPU core of a physical machine (PM), defined in terms of Millions Instructions Per Second (MIPS) rating.
Processor	A Central Unit Processing (CPU) attached to a Vm and which can have multiple cores (Pes).
Ram	Represents the RAM resource of a PM or VM in Mebabytes.
ResourceAbstract	An abstract implementation of a Resource.
ResourceManageableAbstract	A class that represents simple resources such as RAM, CPU, Bandwidth or Pe.
SanStorage	SanStorage represents a Storage Area Network (SAN) composed of a set of hard disks connected in a LAN.
Storage	A simple storage that just manages the device capacity and raw allocated (used) space.
