I am considering consolidating our environment to a Single SQL enterprise
server. I'm curious about how the instances are handled.. if one instance
gets updated how does this impact the other instances that are running. What
effect does this have as far as the master db goes. Is there a single point
of failure in sql that may crash the whole environment? Any help would be
greatly appreciated.
