The slides for my UBC Alumni talk on programming for the Cloud. I show Cloud Foundry as an example of an open cloud platform and how easy it is to create modular, scalable applications using it.

78. A cautionary tale
 Google app engine
• Write your Java/python code
• Use proprietary (but powerful) APIs
• Push app to Google servers
• (Maybe) pay a bit of money

 Uh oh!
• September 2011
• Google (rightfully) wants to turn a profit on GAE
• Mid-2011 pricing change:
• pay for Instance hours, not CPU hours

The Register:
Unloading their anger on the official
Google App Engine mailing list, some
developers have vowed to move their
applications to competing services. But
others have pointed out that because of
the service's unique design, such a
move would itself be quite costly.

128. What’s easy now that I have the cloud?
 Scalability
• vmc instances n
 Power of services
• provision through the command line
 Responsive client
• constant ongoing communication between client and server
• websockets
