Every added 9 to the reliability increases the price exponentially. Finding the correct level of reliability is something most companies should focus more on, because sometimes a single physical machine that could go down once a year for a few hours is perfectly capable of providing all the resources a medium seized business could need. Proper backups, monitoring and recovery runbooks can even decrease the downtime of such a simple system to minutes, while easily saving you maybe thousands per month.
