Desktop Cloud Overview

• Desktop Cloud is a new Cloud type that harnesses non-dedicated computing resources to provide Cloud services.

• Resources can be limited to an organisation or collected from the public

• Desktop Clouds Vs. Traditional Clouds

VM Allocation Mechanism

It is the process of allocating a virtual machine (VM) to a physical machine (PM)

VM requests

Problem Statement

• How to design a mechanism that can improve resource utilisation without affecting Performance

=> Desktop Clouds: in the presence of node failures

• Challenges:– Replication Vs. availability – Migration Vs. cost

The Proposed VM Allocation Mechanism

Experiments

• Experiment I: Desktop Clouds Vs. Traditional Clouds

• Experiment II: evaluate the proposed mechanism

• Experiment III: online optimisation• Evaluation Metrics:

– Performance (Response time & throughput)– Power consumption (Utilisation)– Resource availability
