Install and Execute CloudSim in Netbeans

Download CloudSim-3.0.3(.zip for windows & .tar.gz for linux) from this link.

Extract it cloudSim-3.0.3 compressed file into local system.

In the folder you can find the folder named 'jars', here you can see four jar files.

Now open Netbeans and do the following,

1. File -> New Project  (Shortcut : Ctrl + Shift + N)

2. Select "Java" from categories and "Java Application" from projects, click next.

3. Enter project name, for example 'CloudSimulator'.

4. Select project location for storage and select the option for creating main class with project name(optional;if else you have to create main class manually), click finish.

Now you can see the project 'CloudSimulator' in projects. It will contain a package with same name and main class 'CloudSimulator.java'.

Now right click the project 'CloudSimulator' and select properties,

Select libraries,

Click the button "Add JAR/Folder", go to the path where you are stored cloudsim-3.03 folder, open the folder jars and select jar file named as "cloudsim-3.0.3.jar" click 'OK'.

Now the jar file has been added in your project library, check it and click 'OK'.

Open "CloudSimulator.java" or else create new java class. Select and delete the class with main class.

Now open folder cloudsim-3.0.3, and open examples - > org - > cloudbus - > cloudsim - > examples

Open any one example(CloudExample1.java consists single Datacenter in will increase one by one upto 8 in CloudExample8.java).

I did CloudExample1.java,

Copy the code from imports and paste it into "CloudSimulator.java",

Change the class name from "CloudSimExample1" to "CloudSimulator",

Right click - > Run File (or) Press Shift + F6, and the output will be shown in console,

In code you can edit VM properties,

            // VM description
            int vmid = 0;
            int mips = 1000;
            long size = 10000; // image size (MB)
            int ram = 512; // vm memory (MB)
            long bw = 1000;
            int pesNumber = 1; // number of cpus
            String vmm = "Xen"; // VMM name

You can check with eight example by changing properties and you can get different outputs for every change. Given examples allow you to create upto 8 data centres . And you can add or change in code for different result.

Thank you.

Next time I will show you cloud network simulation using cloudsim.
