The Importance of Reliability...
... the computer system will perform consistently (i.e. not unexpectedly or unpredictably) under different conditions (e.g. hot weather) |
... the computer system will be robust (it does not crash easily/often) |
... there will be a recovery system in place (e.g. a backup server will take over from the primary server if it fails) |
Make sure your computer system is reliable so it doesn't come a cropper!
