Can any one suggest me a good reference/book for simulation process of cloud computing using CloudSim (i.e the coding part) in term of VM allocation or task scheduling in cloud computing;any suggestion appreciated.
You may refer the following to have the complete information of CloudSim (http://www.buyya.com/papers/CloudSim2010.pdf ) - "CloudSim: a toolkit for modeling and simulation of cloud computing environments and evaluation of resource provisioning algorithms".
Further, you may wish to explore CloudAnalyst: A CloudSim-based Tool for Modelling and Analysis of Large Scale Cloud Computing Environments (http://www.cloudbus.org/students/MEDC_Project_Report_Bhathiya_318282.pdf).
