This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.

centre to determine reliability. It is not sufficient to look at the

are being abstracted and delivered in a virtualization fashion. It
cannot be assumed that the configuration of the virtual infrastructure
is resilient and neither can it be assumed that all services are being
delivered in a generic fashion.
