Introduction to Virtualization  Widely used technology  Benefits of Virtualization  Consolidation and isolation  Reduced power and cooling  Green computing  Ease of deployment and administration  High availability and disaster recovery  Many companies, datacenters, organizations, universities, and IT have virtualized their servers.  Even Small business and individuals started using their virtualization solutions.  Availability of Low-cost Public Clouds, e.g. Amazon AWS MCEVE / Abdullah Almurayh 6/30/2011 3

The Problem:  Diversity of virtualization solutions has opened the door to an endless array of choices  Virtualization technologies operate in slightly different manners  Virtualization technologies have different architectures and requirements.  Full-virtualization  Para-virtualization  Operating system-level virtualization  Hardware virtualization  By having vast choices, people sometimes become so confused and unable to choose the right virtualization solutions.

Objectives:  To have suggested solutions in easy way and low cost.  The solutions need to be acceptable and reasonable accordingly to the real world.  A user can get more details about the configurations that are usually used in virtualized environments..  To know the advantages and the disadvantages of suggested virtualized technologies.  A user can get a good overview of configurations that may meet his expectations.  Metrics for evaluating a solution include:  Cost.  Performance. MCEVE / Abdullah Almurayh 6/30/2011 7

The Proposed Solution:  Develop a model for suggesting better solutions of virtualized environments based on the user weighted considerations.  Use user weighted considerations as inputs for algorithmic outputs MCEVE / Abdullah Almurayh 6/30/ Cost Throughput Response time Application Capacity

Recommendation Algorithm: MCEVE / Abdullah Almurayh 6/30/ Start Input { conf0, conf 1, conf 2,…} If (n) Input { measure0, measure1, measure2, …}. Input { weight0, weight1, weight2, …} $best = Max{ Mix 0, Mix 1,…, Mix n } Output ($best) End Yes No Conf : user configuration Weight : user configuration weight Measure : benchmark measurements W : Weight value M : measurement value Mix : overall calculation n : number of existing specification best : best selection of the overall results

Competed Tasks Research done during Fall 2010 :  Research virtualization technology characteristics, types, and architectures.  Read and used some common virtualization platforms.  Demonstrate the possibility of their usability in the real world. Work done during Spring 2011:  Figure out a development algorithm for the Model.  Perform algorithms for generating the Model requirements to represent real world measurements that can be used in the Model.  Research the most important considerations that can be used in the Model.  Collect existing information, facts, considerations, and the like for virtualized environments. MCEVE / Abdullah Almurayh 6/30/

Task in Progress Estimated completion in Summer 2011:  Implement, test, and analyze the Model application.  Perform experiments on the Model and analyzing the accuracy of results.  Report the process of the research with all explanations, facts, implementations, experiments.  Prepare a Demo of the Model in real world and showing how the results can meet a user’s expectations.
