Computing in the Clouds

In his article, "Computing in the Clouds," Doug Johnson makes a case for schools to adopt cloud computing.  Cloud computing relies on applications and file storage that resides on a network.  The network could be a local-area network, a district Intranet, or the Internet.   According to Johnson, the biggest advantage to cloud computing is cost savings.  For schools that are facing budget problems, cloud computing can help cut costs because applications and file storage are free.  Also, schools can invest in cheaper computers, such as Netbooks, because computers operating in the cloud do not need have large hard drives or powerful processors.  Two other advantages of cloud computing are ease in sharing documents and the ability to work anywhere on any computer.

I found the warnings against cloud computing to be fairly benign.  For example, steps have been taken by Google to ensure file security and privacy.  There are some funtions that the cloud cannot handle such as big data crunching projects, but it is unlikely that primary school students would undertake projects like these.  My biggest concern would be that providers of applications and storage may start charging for these services in the future, which would negate Johnson's main argument in favor of cloud computing. 

I found it is also important for schools to consider the following.  First, that they have in place a wireless network that is reliable, adequate and secure to support hundreds of users.  And second, schools must provide teacher training on cloud computing. 

As a teacher, I would advocate for cloud computing as a means for students and teachers to have greater flexibility and to encourage collaboration among students and teachers.  Cloud computing allows teachers to share ideas, concepts and lesson plans with other teachers in their school and within the district.  This kind of sharing and collaboration saves time and makes for better teaching.  Students can also work collaboratively on projects using the cloud.  They can work in groups at school and continue working with their group at home.  These uses of cloud computing support ISTE NETS Standards for Communication and Collaboration (2) and Digital Citizenship (5). 

Overall, cloud computing is an excellent choice for schools looking to save money and encourage communication, collaboration and digital citzenship.  Cloud computing helps schools save money by not having to buy expensive software programs or file storage.  Computers that use the cloud can be cheaper because they do not need big hard drives or powerful processors.  The ability to share files on the Internet encourages teacher and student collaboration and communication.  Finally, I believe cloud computer fosters digital citizenship as stated in the NETS Standards, "students exhibit a postive attitude toward using technology that supports collaboration, learning and productivity."
