Virtual Worlds
“You take the red pill - you stay in Wonderland, and I show you how deep the rabbit hole is.”
- Morpheus, The Matrix
Holodeck on StarTrek Enterprise TNG
Holodeck
● Star Trek: http://en.wikipedia.org/wiki/Holodeck
● A simulated reality, where 3D worlds could be simulated with force fields and projections.
● Load, run, freeze and store programs.

“Computer, end program”
As it was in the beginning
● Mainframe virtualization.● IBM's CP-40 research system in 1967.● Compartmentalize large processing
capabilities.● Run processes separately.● Lease “slices” to different customers.
Too many servers?
● Data center challenges– One physical server for one application
● Web● Storage● Authentication● Network
– Power, Cooling, Bandwidth...– Under-utilization
= 490%
40%20%
50%
Rise of Apache
● Apache VirtualHost.● Multiple virtual web hosts in each physical
server.● Led to the adoption of Apache in server
rooms.● Eventually led to Linux to run these websites.● Still one underlying OS.
Single point of failure?

* as a Service
● Software as a Service (SaaS)– Salesforce.com, GoogleDocs
● Platform as a Service (PaaS)– Google App Engine, Heroku, OpenShift
● Infrastructure as a Service (IaaS)– OpenStack, Eucalyptus, CloudStack
● Metal as a Service (MaaS)– Ubuntu MaaS
Public and Private clouds
Public Private
Hybrid clouds

+Two reasons: Compliance and spillover
Hypervisors galore!
Hypervisors (xen, kvm, vmware, hyper-v, virtualbox, ...)

Start local, go global.
http://virtualbox.org
Build on Virtualbox, Deploy in the cloud.
Virtualbox
An extreme example...
Windows 3.1 on Virtualbox
Note: Some of you may not be old enough to remember this!
Moving VM into the cloud
Windows 3.1 in the cloud!

● Private cloud on multiple nodes– http://commons.sfsu.edu/continuing-openstack-project-phase-2
Owncloud example
Juju commands to orchestrate a OwnCloud instance with a MySQL backend.
$ juju deploy owncloud
$ juju deploy mysql
$ juju addrelation owncloud mysql
$ juju expose owncloud
