Thing #45 -- Cloud Computing

I commented on the rise in web applications in Thing #2. It's an update of early days of computing. Back then, everything was kept on a large mainframe computer, and so-called dumb terminals (basically monitors and keyboards) were hooked up to it. Then desktop computers became more and more powerful, and everything was done locally, using the workstation's own processor and memory. Now we've arrived at cloud computing, which is just the modern day equivalent of the mainframe and not-so-dumb-anymore terminal--applications, documents, all kinds of data, really, are stored on a server somewhere and accessed anywhere via an Internet connection and a web browser.

My primary experience with cloud computing is using Apple's MobileMe service, and account that gives me space on the cloud to store files, and access to my email, calendar, contacts, and photos. My husband and I are able to synchronize between what is on the cloud and all our computers, whether at home, at work, or on our iPods. Eventually we would like to purchase a new router for our home network that would allow us to use the Back to My Mac feature. Then we would be able to access files between computers directly, without needing to upload them to the cloud for sharing first.

For work, I've used both Google Docs and Zoho, and written about them in previous posts. I haven't used Zoho beyond the one, rather unsuccessful, experience. Google Docs, on the other hand, continues to be an important tool as I collaborate on projects with librarians from other instutions.

There's always a tradeoff between access and security, and cloud computing is no different. It's nice to have access to files from anywhere, but that also leaves open the risk of others getting unauthorized access to those same files. Our campus, like most others, has a firewall in place to prevent many kinds of access to campus networks from off-campus. However, as more and more tools I use are web based, I have discovered that I can do increasing amounts of work from home without running into firewall problems. This can be important as the college makes contingency plans for how to continue operations in the event of a swine flu pandemic, or other severe outbreak.
