CloudSim 7 Project

This project is a simulation framework built on top of CloudSim 7, designed to model and evaluate cloud computing infrastructures and services. It allows researchers and developers to test scheduling algorithms, resource allocation strategies, and data center behavior under various scenarios — all without needing access to a real cloud.

Technologies Used

• CloudSim 7 – Core simulation framework for cloud environments
• JDK 21 – Compiled and tested with Java Development Kit 21
• Apache Maven 3.9.9 – Used for project build, dependency management, and execution

Requirements

• Java 21 or higher
• Apache Maven 3.9.9 or compatible version

Build and Run

Clone the repository:

git clone https://github.com/alihamidzadeh/NOSF-Cloudsim.git

Put NOSF source codes src/main/java/org/cloudbus/cloudsim/examples/nosf on your cloudsim-7 Project then build the project with Maven:

mvnd clean install

Run the simulation:

mvnd exec:java -D exec.mainClass="org.cloudbus.cloudsim.examples.nosf.Main"
#OR
mvnd exec:java "-Dexec.mainClass=org.cloudbus.cloudsim.examples.nosf.Main"

⚠️ This project has been tested on Ubuntu 20.04 and Windows 11. It performs better on Ubuntu, and some log entries may not be visible when running on Windows systems!

Log and Workflow Files

• In the Simulations-Log folder, you can find logs of some workflows simulated using NOSF.
• In the Workflows folder, you can find parts of standard DAX workflows for simulation through this project. To use them, simply provide the path to them in the workflowFiles array within the Main.java class, located at src/main/java/org/cloudbus/cloudsim/examples/nosf.
