Oh, the irony! Cloud-to-Cloud Lightning!

Yesterday, in a case of extreme irony, real clouds struck back at human clouds when lightning hit a power transformer at the Amazon Elastic Cloud service in Ireland. "Full service recovery may take 24-48 hours", they said. This outage follows by a few months another significant EC2 disruption caused by a configuration update; not that these unfortunate episodes are unique to Amazon. But they do point to the serious cloud computing issue of putting so many eggs in one cloud basket...what are the availability, recovery, and liability requirements for users of large, multitenant cloud services? Clearly we still have a long way to go in this inevitable move to cloud computing. And such incidents imply that at least for now, cloud users may need to implement alternative availability and recovery technologies in order to mitigate the effects of cloud outages.

The purpose of this blog is to highlight and to explore general issues around "Cloud Computing" -- its benefits, risks, and component technologies -- and how they are evolving. I'll also periodically comment (of course!) on Oracle's Cloud Computing capabilities, resources, and cloud-related events. -- Harry J Foxwell, PhD, Principal Consultant for Cloud Computing, Oracle Public Sector HW
