Increasing Redundancy Is Leading To Zero Downtime
from the department-of-redundancy dept
It's nearing the end of the year, so not surprisingly, there's more talk about what's in store for the next year and the near future. Out of these discussions, one of the interesting points predicts that zero downtime is moving to replace "five-nines" of availability. It's not exactly a new concept to plan backups for when components will fail (not if they will), but redundant hardware components are becoming increasingly common as the costs for them decrease. Spare processors can be activated at will. Entire facilities can be replicated in disparate geographic locations. There may always be unexpected downtime, but the costs associated with them are trending towards being more manageable.
