Har været inviteret til at give en foredrag @ITU ifm Cloud Computing
kursus. Foredraget handlede om implementering af private cloud
løsninger (baseret på OSS) i akademiske miljøer.
Hermed et uddrag fra technical paper jeg har skrevet sammen med min
vejleder ifm et projekt sidste år:
"Guidelines for Building a Private Cloud Infrastructure"
Cloud computing has become an extremely attractive area of
research and practice over the last few years. An increasing number
of public and private sector organizations have either adopted cloud
computing based solutions or are seriously considering a move to
cloud computing. However, there are many concerns about adopting and
using public cloud solutions. Hence, private cloud solutions are
becoming an attractive alternative to a large number of companies.
We initiated a project aimed at designing and setting up a private
cloud infrastructure in an academic and scientific environment based
on open source software. One of the key objectives of this project
was to create relevant material for providing a reference guide on
the use of open source software for designing and implementing a
The primary focus on this document is to provide a brief
background on different theoretical concepts of cloud computing and
then elaborate on the practical aspects concerning the design,
installation and implementation of a private cloud using open source
solution. It is expected that organizations looking at the
possibilities for implementing cloud solutions would benefit from
getting the basics, and a view on the different aspects of cloud
computing in this document. Defining the cloud computing; analysis
of the economical, security, legality, privacy, confidentiality
aspects. There is also a short discussion about the potential impact
on the employee’s future roles, and the challenges of migrating to cloud.
The main part of this report is concentrating on the practical
infrastructure related questions and issues, supplied with practical
guidelines and how-to-dos. The main topic was the design of the
server and network infrastructure, and the distribution of the roles
over the servers belonging to a private cloud. The management of the
instances and the related subjects are out of the scope of this
document. This document is accompanied by three supplemental books
that contain material from our experiences of scaling out in the
virtual environment and cloud implementation in a physical
environment using the available server and networking equipments.
