Cloud Computing

Time-to-Adoption: One Year or Less

The emergence of very large “data farms” — specialized data centers that host thousands of servers — has created a surplus of computing resources that has come to be called the cloud. Growing out of research in grid computing, cloud computing transforms once-expensive resources like disk storage and processing cycles into a readily available, cheap commodity. Development platforms layered onto the cloud infrastructure enable thin-client, web-based applications for image editing, word processing, social networking, and media creation. Many of us use the cloud, or cloud-based applications, without even being aware of it. Advances in computer science to ensure redundancy and protection from natural disasters have led to data being shared across many different hosting facilities. Improved infrastructure has made the cloud robust and reliable; as usage grows, the cloud is fundamentally changing our notions of computing and communication.


Relevance for Teaching, Learning, or Creative Inquiry

  • Cloud-based applications can provide students and teachers with free or low-cost alternatives to expensive, proprietary productivity tools.
  • Cloud computing is being used in schools to provide virtual computers to students and staff without requiring each person to own the latest laptop or desktop machine.
  • Services like Flickr, YouTube, and Blogger, as well as a host of other browser-based applications, comprise a set of increasingly powerful cloud-based tools for almost any task a user might need to do.
