Universidade Federal do Ceará Web Workload Modeling for Simulation and Analysis in Cloud Computing Deborah M. V. Magalhães Group of Computer Networks, Software Engineering, and Systems (GREat) Federal University of Ceara (UFC) Advisor: Danielo Gonçalves Gomes Cloud Computing and Distributed Systems (CLOUDS) Laboratory The University of Melbourne (Unimelb) Co-advisors: Rajkumar Buyya and Rodrigo Calheiros

Universidade Federal do Ceará Motivation Cloud environments have different types of applications –resulting in complex workloads according to users behaviour and task resource consumption patterns Not much real datacenters traces are available (MORENO et al., 2013) –Lack of methodologies to capture the diversity of cloud workload patterns Provisioning and scheduling techniques for interactive applications is an important issue (GROZEV;BUYYA, 2013) Workload modeling in cloud computing gives rise to performance analysis and simulation (FEITELSON, 2003)

Universidade Federal do Ceará Main Goals The creation of a web application model based on data collected from a real Cloud for analysis and simulation, so that there is a good approximation to the real system –A model easily manageable to generate different synthetic loads relating to other relevant applications in Cloud Computing What is the relation between the model creation and energy efficiency (theme 2)?

Universidade Federal do Ceará Workload RUBiS: Rice University Bidding System –An auction site based on eBay.com, implementing basic functionality, such as: selling, browsing and bidding –It is widely used to evaluate scalability of application servers –It is a free and open source benchmark

Universidade Federal do Ceará Short and midterm actions 1.Incorporate the mathematical models extrated from the observed data to the R software 2.Extract the simulation results from CloudSim and evaluate the fit of model to the observed data 3.Investigate the most suitable algorithm for predicting the metric of interest: response time
