Some advantages are: Distributed computer power can solve very large problems that individual computers cannot approach. Distributed data can have instantaneous backups at multiple locations, making mission critical data more available. Distributed application software can be updated dynamically without the worry of individuals performing the updates. Distributed computing permits access to data and software from virtually any location. While some of these advantages are already a reality in limited implementations, not all of them are being implemented across the Internet, yet. As the development of cloud computing progresses, they will. -- Jim

In may last job, I was located in Arizona. My data was in California, Colorado, North Carolina, and New York. Some applications were local to my machine. Others were also on the remote servers. Whether it is the data or the applications are being made available from remote computers makes little difference. All of the servers work together to make data and application computing transparently mobile. From Wikipedia.... Cloud computing is Internet-based computing, whereby shared resources, software, and information are provided to computers and other devices on demand, like the electricity grid. The question asked was "What are some advantages to clouds?" The advantages include the things that I mentioned, including the two points that dealt specifically with data storage. Instantaneous backups at multiple locations, and data available virtually anywhere.

If all the data is on physical storage devices owned by the company running over the Internet as VPN tunnels -- it's not a "cloud" (OK call it an internal cloud). I was doing this 10 years ago, before "cloud" became the latest, greatest buzzword. My definition of "cloud" storage involves giving up control of your data to a third party Internet provided (with or without a VPN). You may not even know what country hosts your data. That's why my original comments apply. You can have all the contractual legalease you want, but if the company sells out or the country wants to snoop, you actually have no recourse and may not even be able to retrieve YOUR data. Your reference to the electricity grid highlights the shared/who really owns question. Who really owns and runs the Internet? That's the rub. My couple of pennies worth...... Regards, sb |
