Server virtualization allows multiple virtual machines to run on the same physical server hardware. It increases hardware utilization and enables server consolidation. The benefits of virtualization include higher utilization, decreased provisioning times, load balancing, improved security, and easier disaster recovery. However, virtualization also increases management complexity and physical hardware failures can affect multiple virtual machines.

Modeling and Optimization of Resource Allocation in Cloud [PhD Thesis Proposal]AtakanAral
As cloud services continue to grow rapidly, the need for more efficient utilization of resources and better optimized distribution of workload emerges. Our aim is to provide a solution to this optimization problem from three perspectives: (1) Infrastructure level; (2) Application level; and (3) Platform level.
In infrastructure level, the problem is to distribute virtual machines (VMs) to the datacenters (DCs) with geographical locations in such a way that latency is minimized while WAN bandwidth and datacenter capacity limits are respected. We plan to model latency as a function of DC load, inter-DC communication and proximity to user. Both VM requests and cloud infrastructure can be represented by graphs where vertices correspond to machines (either physical or virtual) and edges correspond to network connections between them. Our approach will employ weighted graph similarity and subgraph matching to suggest an efficient placement or the list of migrations to reach an efficient placement.
VM request is an input to our optimization in infrastructure level but the requested number and capacity of VMs as well as their inter-connections may not be optimal for a specific cloud service. In application level, on the other hand, we plan to deal with the configuration of the MapReduce programming model (More specifically one of its implementations: Apache Hadoop) especially in terms of number of maps and reduces. Previous work has shown that the optimum configuration depends on the resource consumption of the cloud service and it can be determined by executing a fraction to generate a signature. Our aim is to determine the number of maps and reduces statically by analyzing the design model, source code and/or the input data.
Furthermore, in platform level we aim to analyze the shuffle and scheduling algorithms of the MapReduce system to achieve a better load balancing and less amount communication between nodes. Shuffle is the phase where the output of all map processors with the same key are assigned to the same reduce processor. We will carry out a cost based formal analysis of the existing Hadoop schedulers to determine which scheduler is more appropriate for given costs of map, reduce and shuffle.
In summary, a holistic approach will be carried out to improve the performance of cloud software by optimizing resource allocation. Intended optimizations are on infrastructure level (Resource Selection and Assignment), application level (Map Reduce Configuration) and platform level (Work Distribution and Load Balancing). Cloud environment and resource allocation problem will be modeled based on graphs and automata, and the solutions will be within this context as well.
Virtualization began in the 1960s, as a method of logically dividing the system resources provided by mainframe computers between different applications. Since then, the meaning of the term has broadened. <a>
One can Study the key concept of Virtualization, its types, why Virtualization and what are the use cases and Benefits of Virtualization and example of Virtualization.
In recent years, we have seen an overwhelming number of TV commercials that promise that the Cloud can help with many problems, including some family issues. What stands behind the terms “Cloud” and “Cloud Computing,” and what we can actually expect from this phenomenon? A group of students of the Computer Systems Technology department and Dr. T. Malyuta, whom has been working with the Cloud technologies since its early days, will provide an overview of the business and technological aspects of the Cloud.
This presentation tries to explain basics of virtualization, what is server virtualization ? why is it important ? how it is done ? What are the limitations and risks associated with it ?

Introduction to Virtualization and Server
Virtualization
Comparing with and without virtualization
Virtual server concept
Benefit of server virtualization
Limitation of server virtualization
4. What is Virtualization
Server virtualization
Creates multiple isolated environments
Allows multiple OS’s and workloads to run on
the same physical hardware
Virtualization basically allows one computer
to do the job of multiple computers, by sharing
the resources of a single hardware across multiple
environments.Version of virtualization such as
hardware platform,operating system,storage
device , network resources and server

6. The Traditional Server Concept
Old Model:
Traditional x86 Architecture
• Single OS image per machine
• Software and hardware tightly
coupled
• Multiple applications often
conflict
Old model is challenging!

7. Comparison between with and
without virtualization
With VirtualizationWithout Virtualization
VMware provides hardware virtualization that presents a complete
x86 platform to the virtual machine
Allows multiple applications to run in isolation within virtual machines
on the same physical machine
Virtualization provides direct access to the hardware resources to
give you much greater performance
8. The Virtual Server Concept
Hardware independence
–Guest VM sees the same hardware
regardless of the host hardware
Isolation
–VM’s operating system is isolated
(different) from the host operating
system
Encapsulation
–Entire VM encapsulated into a single
file
Virtual machines provide:
