One good example of cloud computing is web-based email. Services such as Gmail, Aol and Hotmail keep all of your messages on their servers, and you access your email through the web. Music services that let you access many different songs through the internet, including Pandora and Spotify, are another type of cloud computing.Cloud storage services, such as Memopal and Box, keep your data stored on their servers, freeing up your hard drive space.
