Yes we know what Cloud Computing is
But I'm not sure that your question is answerable in any fashion that doesn't rely on Personal Opinions.
The facts are that you are not hosting your Data so you have no control over it. If the company who is hosting it gets Cracked or has a Hardware Failure your Data is gone. Or worse it's sold on to your competition.
If there is any Complacencing Issues the Cloud is most likely out of the question for nothing more complex than the simple fact that you do not control your Data. So places that rely on even Basic Security fail to meet the requirements involved in getting Accredited.
Also you need to understand that when your local country Infrastructure even the globe depending on where the data is stored in the end goes down so does you're Computing Abilities so a Power Failure that doesn't directly affect you can kill your Data Storage or say for argument sake your Data is hosted in China and it was in an area affected by the recent Earthquake it may be months or longer before that location is up and running again. The idea with the cloud is that the data moves around as places drop on and off the cloud but the reality is that when you pay a company they have their preferred resellers who have their preferred resellers and so on and you tend to end up with very limited possibilities for where your Data & Services actually are. Most chose the cheapest locations available. 
Then something as simple as a bulldozer bringing down a Line can kill your Internet Connection and hence your computers and Data Store for anything from a few minutes to weeks depending on how severe the damage actually was initially and what has happened as a result of that damage. Recently here one of the Telco's had their Optical Fiber Trunk Line dug up which immediately killed that service and the resulting Backup was overloaded which brought that down for the best part of a day till they could get the Fiber Cable repaired. Their Wired Backup took quite a bit longer to get up and running but the customers and end users didn't notice as they routed a lot of the Wired traffic over the optical fiber cable .

It's not - the technology, as promoted, is very new and has
How Secure & Reliable Cloud Computing
my company just start to look new technology that can help us to solve IT problem
i hear what it call cloud computing, after i read some source i have a lot question about this technology
how far cloud computing is secure and reliable?? i am quite agree with Richard Stallman's for his opinion that cloud computing less secure for sensitive company data to be host on internet
i am open to discuss
thank you
