HUMAN FAILURE
Keith Edmunds is MD of Tiger Computing Ltd, which provides support for businesses using Linux.
In any business system you want to eliminate as many single points of failure (SPOFs) as possible. That’s why we use RAID systems for disks: if one disk fails, then (so long as our monitoring is fit for purpose) we will know and can fix it, but the service continues without interruption and so your business can continue with no disruption to its smooth-running processes or your customers.
