Introduction

This wiki web page documents the possible implementation of the OpenStack cloud infrastructure (IaaS) using the Ubuntu server operating system, in order to evaluate the possible deployment as a private on-campus cloud for the Stellenbosch University Library. See: http://en.wikipedia.org/wiki/Cloud_computing

A brief overview of OpenStack is displayed below.

OpenStack Provisioning

MAAS (Metal As A Service) is the service from Ubuntu which provides easy installation of metal servers to the OpenStack cloud and provides the "Standard Hardware" layer pictured above. Once the metal servers are provisioned then "Juju" charms are used to install components of the OpenStack cloud which provides the "OpenStack Shared Services" layer pictured above. Finally cloud services ("Your Applications") are provided by the "OpenStack Dashboard" pictured above.

OpenStack Demo Server Download

A live CD of the demo server can be downloaded from the following link:

http://cdimage.ubuntu.com/ubuntu-cloud-live/releases/12.04/ubuntu-12.04-cloud-live-amd64.iso

OpenStack Demo Server Instructions

These instructions apply to a 64bit computer registered on the campus network and should be applied by someone experienced with linux system administration.

  1. Create a bootable USB stick from the CD and then boot your test computer with the USB stick.
  2. After booting the USB stick on your test computer, open the Google Chrome browser on the Unity Launcher and open an internet connection by going to https://inetkey.sun.ac.za.
  3. Open the "GettingStarted" file on the desktop and follow the instructions.
  4. The credentials for logging into the "Dashboard" are:
username = ubuntu
password = ubuntu123

Calculation

As can be seen from the above screenshots, the average price per GB is approx R1 as per the exchange rates on 2012/08/07. In addition it costs about R2 per GB to pull the data back out of the cloud.

Therefore to store 6TB (6000GB) in the cloud per year costs the following at today's exchange rates (2012/08/07):

R1x6000X12=R72000

Note: One double-sided DVD can store 8GB of data, therefore 6TB=750 double-sided DVD's or 1500 single-sided DVD's of data.

Amazon Glacier

Amazon Glacier is an extremely low-cost storage service that provides secure and durable storage for data archiving and backup. In order to keep costs low, Amazon Glacier is optimized for data that is infrequently accessed and for which retrieval times of several hours are suitable.

Conclusion

OpenStack is an early project but it is fully open source and based on open cloud standards. CloudStack is a product, however it is "owned" by Citrix, therefore not an open product.
