Cloud Types
http://www.52north.org/wpsFOSS4G 2009
Provider
• Amazon Web Services– Virtual (Machine) Computing Environment– Simple Storage Service (Amazon S3), SimpleDB,
Elastic Compute Cloud (Amazon EC2), Elastic MapReduce, etc.
– „0,10$ / hour“ for an running virtual system• Google App Engine
– Web applications written in Java and Python– Storage Service, Google Applications (Mail, Account)– „0,10$ / hour“ for real CPU usage
• Microsoft, Apple, SUN, IBM, Salesforce, etc.

Projects
• DMTF Open Cloud Standards Incubator
• The Open Cloud Consortium (OCC)
• Open Cirrus - Open Cloud Computing Research Testbed
• Open Cloud Manifesto

SDI to Cloud Transition
http://www.52north.org/wpsFOSS4G 2009
SDI to Cloud Transition
• CloudSDI vs. SDICloud
http://www.52north.org/wpsFOSS4G 2009
SDI concepts
• Technical / Service Perspective
SDI provides georesources through standardized interfaces over a service infrastructure

Major Obstacles
• IT investments & maintenance
• Mass market
• Legally Binding Performance
http://www.52north.org/wpsFOSS4G 2009
IT investments & maintenance
• High investments
<hardware, software, humans>
(for seldomly used tasks)outtasking & on demand use
e.g. Taiwan Debris Flow, French SDI Portal
