Before the new cloud services concept appeared, everything related to storage and processing was done on a local computer. That is to say, we had to install the necessary software in our laptop to get services to work properly. Thanks to the cloud service, we can now precisely distinguish between that software we are supposed to install locally, and tools use. In that way we do not need to use apps or remote programs, since they’re storaged online.
Even if we don’t realiase, day a day we use a big amount of cloud services such as Amazon, Apple, Yahoo, Netflix, Spotify… and we can access to all of them from any device. As you can see the Cloud is closer than we think.
