Historically, for software to run on a computer, an individual copy of the software had to be installed on the computer, either from a disk or, more recently, after being downloaded from the Internet. The concept of “cloud” computing change this, however.
To understand cloud computing, we first have to understand what the cloud is. “The cloud” refers to applications, services, and data storage on the Internet. These service providers rely on giant server farms and massive storage devices that are connected via Internet protocols. Cloud computing is the use of these services by individuals and organizations.
You probably already use cloud computing in some forms. For example, if you access your e-mail via your web browser, you are using a form of cloud computing. If you use Google Drive’s applications, you are using cloud computing. While these are free versions of cloud computing, there is big business in providing applications and data storage over the web. Sales force is a good example of cloud computing – their entire suite of CRM applications are offered via the cloud. Cloud computing is not limited to web applications: it can also be used for services such as phone or video streaming.
Advantages of Cloud Computing
• No software to install or upgrades to maintain.
• Available from any computer that has access to the Internet.
• Can scale to a large number of users easily.
• New applications can be up and running very quickly.
• Services can be leased for a limited time on an as-needed basis.
• Your information is not lost if your hard disk crashes or your laptop is stolen.
• You are not limited by the available memory or disk space on your computer.
Disadvantages of Cloud Computing
• Your information is stored on someone else’s computer – how safe is it?
• You must have Internet access to use it. If you do not have access, you’re out of luck.
• You are relying on a third-party to provide these services.
