VMware's second-day problem illustrated the element of human error in cloud networks, just as the root-cause analysis of Amazon's cloud outage did. In the case of Amazon, a mistake made during a system upgrade led to trouble that took several days to fully correct.
VMware, which is best known for its server virtualization technology, is a new player in offering a publicly available cloud service. Previously, VMware sold technology to help customers and service providers build their own clouds.
Because Cloud Foundry is so new the customer impact was not as severe as the one caused by Amazon, whose outage forced offline numerous websites that rely on Amazon infrastructure. But VMware is getting a taste of what it's like to be a service provider when things go wrong.
