CloudSim Toolkit for Cloud Computing Modeling and Simulation
"Explore CloudSim, a toolkit for modeling and simulating cloud computing environments with a focus on resource provisioning algorithms. Learn about VM allocation, cloud federation, and various simulation scenarios in cloud management. Discover provisioning policies, network communication flows, and overhead evaluation in the cloud environment. Dive into a case study on workload migration and engage in discussions on modeling notations, domain-specific modeling, and modularity in cloud simulators."

CloudSim: a toolkit for modeling and simulation of cloud computing environments and evaluation of resource provisioning algorithms Calheiros et al. - Softw. Pract. Exper. 2011 Presented by Ramy Shahin March 12th2018
CloudSim Simulation Scenarios Resource Management Simulation Discrete Event Simulation
CloudSim Different aspects are modeled and simulated: VM allocation The cloud market Network behavior Federations of clouds Dynamic workloads Data center power consumption Dynamic entity creation
Provisioning Policies Space-shared for VMs Space-shared for tasks Space-shared for VMs Time-shared for tasks Time-shared for VMs Space-shared for tasks Time-shared for VMs Time-shared for tasks Each of vm1 and vm2 require 2 cores: - t1, t2, t3, t4 run on vm1 - t5, t6, t7, t8 run on vm2
Network Communication Flow Network topology description in BRITE format Latency matrix generated per scenario
Federation Case Study Workload migration scenario 25 VMs with 1 cloudlet each
Discussion Modeling and Simulation: What would make a modeling notation/environment more suitable for simulation? Domain-Specific Modeling: Taking CloudSim as an example, how much of such a system can be built on top of a general-purpose modeling system? What pieces would require a DSL? Model/Simulator modularity and interoperability: network topology simulator, cloud simulator, provisioning simulator, federation simulator, etc
