Computing in the Cloud
Computing in the Cloud
Cloud computing means that data, applications, and even resources are stored on
servers accessed over the Internet rather than on users’ computers, and you access only what
you need when you need it. Many individuals and companies are moving towards “the
cloud” for at least some of their needs. For example, some companies provide space and
computing power to developers for a fee. Individuals might subscribe to a backup
service such as Carbonite or Mozy so that their data is automatically backed up on a
computer at the physical location of those companies. Google Docs and Microsoft Web Apps
provide both free and paid versions of various applications that you access by logging in
to their Web sites. For now, these applications are not as robust as the applications you
install on your own machine, but that is likely to change in the future.
In addition to using services over the Internet, many people store fi les on servers
accessed over the Internet. For example, SkyDrive is space on Windows Live servers
where you can store up to 25 GB of fi les in public or private folders or in folders that
you make available to only people you specify. To access SkyDrive, you need a Windows
Live ID. Figure 31 shows the SkyDrive page that appears when you sign in.
