How Does Cloud Computing Effect Mobile Phones?

What is cloud computing? It's a way to organize and utilize all your technical devices. According to Wikipedia, "End users access cloud-based applications through a web browser or a light-weight desktop or mobile app while the business software and user's data are stored on servers at a remote location."

 How does this relate to mobile phones? They are part of the link, especially when it comes to giving remote directions to other devices. It's sort of like having your own world wide web for you and your associates. Storing data from a cell phone or iPad by using cloud storage has several advantages. First it saves space by not taking up valuable data space on the phone. If the phone is lost or stolen the data has been saved. It's a more secure storage rather than sending data by e-mail or text through the airwaves where it could be intercepted. Lastly as with the other devices in your platform infrastructure (see diagram above), the data will be easy to access from any other source. According to a recent article by Lindsey LaManna published in Business Innovation from SAP  "Thousands of businesses are making the switch from on-premise to the cloud. According to recent research, almost 60% of companies are already in the cloud and an additional 20% are planning to do so within the next 12 months."  One last comment - how secure are the cloud storage locations? So far I've not seen anything written about preventing cloud hacking. Where exactly are these clouds? It seems to me that if multiple companies are storing data in one place it could be disaster as well as a good thing.
