Problem Statement Today’s use of information technology services in daily business poses a daunting task for companies to minimize overhead operating costs while requiring a large amount of resources at varying times. To address this issue utility computing provides a technique for optimization of existing resources to allow for multiple companies to share resources depending on their current demand.

Utility Computing Synonyms: On-Demand Computing & Commodity Computing Providing computing cycles as a resource that can be monitored and charged based on usage Virtualization of the resources 4

Utility Computing Example OnLive Video Games 5

On-Demand Cyber Infrastructure 6

Amazon Elastic Compute Cloud (EC2) Provides virtual machines on request Virtual machines are controlled via web services Root access is available to configure the virtual machines as server Flexible options from virtual machine specifications Reserved instances available when demands surge 7

Nimbus Infrastructure-as-a-Service software package Supported by Globus Provides a interface to share grid resources Utilizes Xen virtualization platform Integrates to Amazon EC2 Launches self-configuring clusters on top of the grid 8

Eucalyptus Project Elastic Utility Computing Architecture Linking Your Programs To Useful Systems Interfaces to the Amazon EC2 Linux image hosted on EC2 Creates cluster on the EC2 and provides the complete underlying infrastructure with a virtual LAN Provides the interface to access these clusters 9

Comparison On-Demand Cyber Infrastructure: Creates virtual infrastructure and machines for a cluster on the ESXi server Instantiates a Cyberaide shell to provide access to virtual machine cluster Amazon EC2: Provides computing resource via virtual machines Nimbus: Allows an existing cluster to be available for on-demand resource request Capable of using VM from EC2 to make the computing cloud infrastructure Eucalyptus: Creates virtual clusters on the EC2 10
