Security experts have warned that the cloud could suffer the same kind of collapses that plague the financial system. Bryan Ford at Yale University in New Haven says that the full risks of this migration have yet to be explored. Complex systems, such as the Cloud, can fail in many unexpected ways and outlines various simple scenarios in which a cloud could come unstuck.
He said that a cloud could experience a full meltdown that could threaten any business. Ford said that while individual systems on a cloud might play nice, if you have other application providers in the same cause problems for another. He came up with a scenario were two conflicting load balancing programs operate with the same refresh period and when these periods coincide, the control loops start sending the load back and forth between the virtual servers in a positive feedback loop.
He said that “This simplistic example might be unlikely to occur in exactly this form on real systems—or might be quickly detected and “?xed” during development and testing—but it suggests a general risk.” Ford said that similar problems happened during ?nancial industry crashes.

Security firm fighting the dreadful Conflicker worm claim that they have it on the ropes. The team of computer-security researchers said they managed to neutralize the worm’s impact by blocking its ability to communicate with its developer, who is still anonymous.
Unfortunately after years of trying fighting the Conflicker, security experts estimate the worm infects between five million to fifteen million computers. The Conficker worm, showed up in 2008. The worms intent is to disable a computer’s security measures, including Windows software updates and antivirus protection, leaving machines vulnerable to more malicious software. Read more….
