Cloud Data centers aim to provide reliable, sustainable and scalable services for different requests. Resource scheduling is a key part for Cloud services. To simplify the scheduling process, we propose FlexCloud, a new flexible and scalable simulator that enables simulating the process of initializing cloud data centers, allocating virtual machine requests, and providing performance evaluation for various scheduling algorithms.

MCloudSim(formerly called NovaCloudSim) is a simulator written in Java for geographically distributed clouds. The software is modified from CloudSim 3.0, which is an open source data center simulator. All functions of CloudSim are reserved, and our newly added files are in the package org.cloudbus.cloudsim.nova. MCloudSim has following characteristics: (1) The overlay protocol can be freely replaced, and we have already ported Pastry, Kadmelia, Chord from PeerSim; (2) A Petri-Net workflow theory based task model is implemented to simulate distributed tasks; (3) A distributed cloud can be easily built by assembling and expanding the basic resource entities provided by the simulator...
