Cloud computing - changing how we use technology

This type of technology usage is very different..but that is nothing new. Technology is changing so rapidly, it's difficult for anyone to stay on top of it all. Cloud computing offers information technology as a service. Users can access documents or data they've stored on someone else's infrastructure. And, they can access software applications from any electronic device that provides Internet access. This type of service allows small companies to use specialized software that otherwise might be beyond their financial capabilities. Various types of specialized software are available in the cloud and it's called "software as a service" or SAAS.
The concept of providing information technology as a service can be compared to homeowners purchasing electricity. In hot and humid weather, the air conditioner comes on frequently. Homeowners pay for electricity that is used. When the air conditioner cycles off, no electricity is being used and the homeowner is not charged.
The same concept applies to cloud computing. Users tap into the cloud to retrieve documents and/or data stored there, or to use software programs that are made available, or for email or Web applications. While connected to the cloud, the user is charged for services. But when disconnected from the cloud, the charges stop.
In addition to SAAS, cloud computing can also include the development of software as a service. Essentially, users run their applications on someone else's infrastructure. Users can opt for a cloud of their own - a private cloud provides proprietary service to a limited number of users. Or other users may decide on a public cloud, whose service can be sold to anyone with Internet access.
There are benefits to cloud computing and it is often attractive to small businesses, school districts and local governments. Some costs for hardware are reduced or eliminated, meaning no capital investment. And, in some situations, the need for in-house technology expertise is reduced.
However, cloud computing is not without its detractors. Some users, CIOs and government officials question reliability, performance and security for platforms they don't own or control. Others have no interest in a service that cannot be customized to meet specific needs. Whatever one believes, it will be interesting to see how this all plays out in the near future. Without doubt, we are witnessing technology changes that have potential for far reaching consequences.
