This document discusses cloud computing and provides guidance for using cloud services. It outlines key principles of cloud computing including on-demand self-service, broad network access, resource pooling, rapid elasticity, and measured service. The document provides a traveler's guide for using cloud services, including knowing what data you own, assessing different options, and making a central gathering point. It also discusses considerations like technical support limitations and potential legal issues when using cloud resources across different jurisdictions.

6. “ The interesting thing about cloud computing is that we’ve redefined
cloud computing to include everything that we already do. […]
The computer industry is the only industry that is more fashion-driven
than women’s fashion. Maybe I’m an idiot, but I have no idea what
anyone is talking about. What is it? It’s complete gibberish. It’s insane.
When is this idiocy going to stop?”

16. Know Thyself
Web 2.0 and cloud computing
•
applications often have strong
social components
What you do online forms a
■
part of your identity
Identity transcends
■
individual applications
Be aware of yourself and your
•
roles
Use different accounts for
■
different facets
Use the same account name
■
across sites to join identities

Own Your Data
Ownership and availability of data are big issues in cloud computing
•
Make sure there is reasonable access to your data
•
Keep copies of your work
■

19. Assess Your Options
Don’t focus on individual
•
applications and services
Be willing to explore
•
Understand what applications
•
work with, not just what they do
Permanence is not guaranteed
•
Google Lively
■
Geocities

23. Technical Support
Self serve, self manage
•
Some services have little to no points of contact
•
UCIT does not provide direct support for non-UCIT resources
•

24. Real World Issues
Cloud computing is “anywhere, anytime” but, legal issues may exist
,
•
Many services are based in the United States
■
Local and foreign laws apply
■
Opaqueness of cloud offerings pose challenges
•
Service providers may themselves be cloud clients
