Well in any conference I walk people are concerned about security with cloud but I tried to prepare more with this list..Watch on!

• Performance. The recent problems with Twitter (“Fail Whale”) and Steve Jobs’ embarrassment at the network outage at the introduction of the new iPhone don’t exactly impart warm fuzzy feelings about the Internet and network performance in general. An SLA can’t guarantee performance; it can only punish bad performance.
• ROI: What has driven the initial stages of cloud computing (that is, software-as-a-service and, to a lesser degree, infrastructure-as-a-service) makes sense mostly as a function of short-term return-on-investment. And isn’t it funny how initial cost savings always seem to dry up over time?
• Market churn. Remember the dot-com boom? Something like that is taking shape in the cloud market, and will be followed by the inevitable slump (bust, crash, etc.). The cloud vendor you were counting on suddenly packed his tent and slipped quietly into the night? Now what? And who has your data? This does not go for big players like Microsoft, Amazon.
• Privacy. Don’t be lulled into thinking the cloud vendor assumes all liability for privacy problems.
• Security. Of course the biggest of all, this is still a problem. When email was introduced everybody raised the same concern but where are we now...so choice is yours..

As per definition on wikipedia, it is " 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."

As per IBM, "Cloud Computing is an emerging model where users can gain access to their applications from anywhere through connected devices"

Sounds tough???

Well it does atleast to me. Now lets look what I have got to know about it:

Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.


Cloud computing is at an early stage, with a motley crew of providers large and small delivering a slew of cloud-based services, from full-blown applications to storage services to spam filtering. Yes, utility-style infrastructure providers are part of the mix, but so are SaaS (software as a service) providers such as Salesforce.com. Today, for the most part, IT must plug into cloud-based services individually, but cloud computing aggregators and integrators are already emerging.
