Interesting project, IMHO to start building your own EC2-like cloud environment

Elastic Computing, Utility Computing, and Cloud Computing are (possibly synonymous) terms referring to a popular SLA-based computing paradigm that allows users to "rent" Internet-accessible computing capacity on a for-fee basis. While a number of commercial enterprises currently offer Elastic/Utility/Cloud hosting services and several proprietary software systems exist for deploying and maintaining a computing Cloud, standards-based open-source systems have been few and far between.

EUCALYPTUS — Elastic Utility Computing Architecture for Linking Your Programs To Useful Systems — is an open-source software infrastructure for implementing Elastic/Utility/Cloud computing using computing clusters and/or workstation farms. The current interface to EUCALYPTUS is interface-compatible with’s EC2 (arguably the most commercially successful Cloud computing service), but the infrastructure is designed to be modified and extended so that multiple client-side interfaces can be supported. In addition, EUCALYPTUS is implemented using commonly-available Linux tools and basic web service technology making it easy to install and maintain. Overall, the goal of the EUCALYPTUS project is to foster community research and development of Elastic/Utility/Cloud service implementation technologies, resource allocation strategies, service level agreement (SLA) mechanisms and policies, and usage models. The current release is version 1.0 and it includes the following features:

  • Interface compatibility with EC2 Simple installation and deployment using Rocks cluster-management tools
  • Simple set of extensible cloud allocation policies
  • Overlay functionality requiring no modification to the target Linux environment
  • Basic "Cloud Administrator" tools for system management and user accounting
  • The ability to configure multiple clusters, each with private internal network addresses, into a single Cloud.

The initial version of EUCALYPTUS requires Xen to be installed on all nodes that can be allocated, but no modifications to the "dom0" installation or to the hypervisor itself.
