Building a private cloud with Eucalyptus

Scientists very often have specific requirements regarding the IT services to support their research and very often standardized offerings of their service providers do not fit. At KIT we aim to build a private cloud to offer flexible infrastructure services that can easily be utilized and managed by end users according to their needs. With Eucalyptus, an open source solution exists that is fully compatible with Amazon EC2, S3 and EBS. This paper compares the performance of a cloud computing infrastructure implemented with Eucalyptus to Amazon EC2/S3/EBS and includes the lessons learned while building up a private cloud with Eucalyptus.
