Evernote .com Familiar web-based cloud services include Facebook, Delicious and Google Reader by Jerry Yarnetsky Flexibility These services can provide a highly flexible, mobile and collaborative computing environment for users. On top of an infrastructure of storage, networking and computing power, you can build a wide range of Internet-based services and applications... Rather than work with software installed on your computer, cloud-based services operate and save data to remote servers. Research applications utilizing this approach include Evernote, a note capturing program, and the Zotero citation plug-in for the Firefox browser. Share and Collaborate Sneakernets are obsolete when data is available worldwide at an instant and you can share in real time Scientific sharing Instant peer review Collaborative editing Planning magic NASA uses the cloud storage to distribute photos from the lunar reconnaisance orbiter. Students post assignments to a class blog where their cohorts offer feedback in the comments. Conferences become democratic when you can collaboratively plan with attendees using a wiki. Open a remote document and see the changes made by the other party instantly. Wikipedia says a sneakernet is a tongue-in-cheek term used to describe the transfer of computer files from one computer to another by means of physically carrying the files on removable media, such as a floppy disk or flash drives to the other computer. This is still an important method for when the cloud is raining on our parade. Many work with cloud services via a web browser Working on the cloud eliminates the fixed costs and labor of installing servers.
You pay only for what you use.

This can ease tight budgets, allow for quick implementation of new services and lower the barriers to adoption.

This allows us to focus on
providing services to
our students. Here This means you can work
anywhere you access the Internet... cc-by-sa 3.0 by Sam Johnston While the possibilities of
cloud computing are
endless, there are also.... Data access & lock-in What is the company's track record for server up-time? Even Google has outages with Gmail.
Does the service lock your data in proprietary file formats or can you easily download your data in a usable format? Web applications and servers can crash. What is the frequency and redundancy of data back up? Research your choices before hopping on the cloud Data loss Privacy Issues How is the hosting using the data?
How does use of cloud computing dovetail with your institution's policies? While many cloud services are inexpensive or free. Others are subscription-based and in the long-run may actually be more expensive than the alternatives. Cost Hybrid models If you have the expertise, consider hybrid cloud models.
Rent web space and install your own applications.
Your institution may operate a private cloud for student, faculty and institional use.
The biggest advantage of a hybrid or private cloud is control over your data which may outweigh other considerations. Thank you! This presentation was created at prezi.com -- a cloud-based presentation application. Images via clipart.com, NASA and Wikimedia Commons.
