Essentially, the cloud should rain raw computing power when called upon. You should be able to scale all computing resources on demand ______________________ Mwendwa Kivuva, Nairobi, Kenya twitter.com/lordmwesh On 14 April 2014 17:31, Tech List Kenya <techlistkenya@gmail.com> wrote:

Techlistkenya,
It's interesting you should mention clouds now, I had the very same question last week. From what I've learned, cloud is different in that it works like a raid array. A cloud OS is installed across several servers (one being the controller) and then a hypervisor (Vmware or Xen) is installed on top of that and finally operating systems are installed inside that. The cloud OS treats the servers (hardware) like they are one big server, just like a raid controller treats several disks as one.
So, in case one of the servers goes down then services are still available. Also 'clouding' helps with load balancing. Resources like storage space and processing power are divided across all hardware and any that isn't needed can even be turned off.

Guys,
I think am getting confused by the cloud jargons. What exactly is the difference between private cloud and datacenter?
I am using the term data centre very loosely here to mean the corporate internal IT infrastructure
There is a lot of talk about setting up private clouds yet in my opinion this has been there for ages. Doesn't corporate file server, exchange server, etc constitute a private cloud?
