Are security issues delaying adoption of cloud computing? "Yes, security is one of the concerns about cloud computing that is delaying its adoption," says Eric Mandel, CEO of managed hosting services provider BlackMesh in Herndon, Va. "One of the biggest security concerns about cloud computing is that when you move your information into the cloud, you lose control of it. The cloud gives you access to the data, but you have no way of ensuring no one else has access to the data. How can you protect yourself from a security breach somewhere else in the cloud?"

Cisco's Chambers: Cloud computing a 'security nightmare' Cisco CEO John Chambers painted a less-than-sunny view on cloud computing security at RSA, saying that "it can't be handled in traditional ways." Cloud computing a 'security nightmare,' says Cisco CEO If anyone has the right to be excited about cloud computing, it's John Chambers.

McKinsey Cloud Computing Report Conclusions Don't Add Up McKinsey, the doyen of strategy consultants, published a report on cloud computing last week featuring a disguised real-world case study. While the report doesn't explicitly state the fact, it seems that the paper is a summary of the results of a strategy project with a financial services firm, which apparently engaged McKinsey to assess whether it would make sense to move all of its systems to Amazon Web Services.
