The idea behind cloud computing is to deliver Infrastructure-, Platformand
Software-as-a-Service (IaaS, PaaS and SaaS) over the Internet on an easy pay-per-
use business model. The Hochschule Furtwangen University (HFU) is running
their own private cloud infrastructure, called Cloud Infrastructure and Application
CloudIA. The targeted users of the CloudIA project areHFU staff and students running
e-Learning applications, and external people for collaboration purposes. Therefore, in
this paper, we introduce our work in building a private cloud. More specifically, this
paper shows how our cloud offerings in each of the cloud service models, i.e. IaaS,
PaaS and SaaS, address the requirements and needs of e-Learning and collaboration
in an university environment.
