CloudSim

CloudSim is a simulation toolkit used to model and analyze cloud computing environments. It allows researchers and developers to test how different cloud resources, like servers and storage, behave under varied workloads without needing real hardware. By creating virtual data centers and simulating user activities, CloudSim helps optimize cloud infrastructure, improve efficiency, and evaluate new ideas before deployment in actual cloud systems. This way, organizations can experiment safely, reduce costs, and enhance their cloud service performance with informed insights.
