Cloud Computing

This page is the main source for lectures, lab-handouts and assignments. This course will cover a mix of business-oriented material about the growth of Cloud Computing; and technical material describing how to build your own Cloud platform using the standard Linux/Apache/Tomcat/Servlet/MySQL technology stack offered on the DCS OpenNebula private cloud infrastructure.

Lectures are provided as powerpoint slides (the primary format, with active links to videos, when viewed in presentation mode) and also as PDF handouts (printed 2-up to save paper).
Lab practical work will start with training sessions for those unfamiliar with Linux, HTML, permissions and web-development. Please watch the lab schedule for new labs relevant to your needs.
The assessment for this module is a group assignment, the details for which will appear at the end of week 3. You will need to work in teams of 4, and a team sign-up system will support this.
