The GreenCloud cloud simulator
GreenCloud is also getting famous in the international market as the cloud simulator that can be used for energyaware cloud computing data centres with the main focus on cloud communications. It provides the features for detailed fine-grained modelling of the energy consumed by the data centre IT equipment like the servers, communication switches and communication links. GreenCloud simulator allows researchers to investigate, observe, interact and measure the cloud’s performance based on multiple parameters. Most of the code of GreenCloud is written in C++. TCL is also included in the library of GreenCloud.
GreenCloud is an extension of the network simulator ns-2 that is widely used for creating and executing network scenarios. It provides the simulation environment that enables energy-aware cloud computing data centres. GreenCloud mainly focuses on the communications within a cloud. Here, all of the processes related to communication are simulated at the packet level.
