OpenStack is an open-source cloud framework for building on-demand
Infrastructure as a Service.
This tutorial in essence distills from this two-page set of instructions for
setting up devstack on a single server primarily for use by developers.
I used a DELL 1950 with 8 GB of RAM, internal hard-drives and two 1000 MB
Download and Set Up Ubuntu
Download Ubuntu 11.10 from here and burn to DVD Boot the server from the DVD
and start the install. I installed the BASE SYSTEM and only one optional
package, the OpenSSH Server. I named my server "ubuntu-server" I configured

HOST_IP address of devstack. Create a user named "stack". Log in as "stack"
See next page for how to Install Devstack...

Project NOVA, or OpenStack Compute, provisions and manages on-demand virtual
machines and associated resources: CPU, Memory, Disk and Network.
Virtual machines can be started, stopped, suspended, created and deleted,
while network options for a ... (more)
Following my introduction to Infrastructure as a Service (IaaS), I published
a review Microsoft Azure IaaS on the WindowsITPro website here:

A first-degree direct LinkedIn connection implies that the two parties know
Using this assumption, two unconnected LinkedIn users attempt to connect via
an intermediary. What often happens is that the first degree connections are
in fact very weak connections, and thus of no use to the third party
attempting to connect via the intermediary.
I log into LinkedIn and would like an introduction to Brent.
I view Brent's profile and notice that his first degree connection, Brian, is
also a first degree connection with me.
So I ask Brian for an int... (more)
