Datacenter computing isn’t a collection of random boxes, it’s a compute grid. Of course, for this to all make sense, software must be built with the datacenter in mind. Good IT shops understand this, and bad ones go t

The admins profusely apologize for this failure, sell their management on a cluster (-f_ck) at five times the price of the original server. The cluster, being less reliable than the original server, proceeds to fail in a more subtle, less recoverable way, taking the service down again. The admins,
