- Increasing automation in the data center can be one of the best ways to reduce errors in a dynamic production environment.
- Automation can also be a source for problems of a much greater scale because of the number of processes that can affected by errors within a large and complex environment.
It’s highly unlikely that American sociologist Robert Merton was thinking about cloud computing when he proposed his “Law of Unintended Consequences” in 1936, but it seems particularly apt in light of Microsoft’s revelations regarding the major Azure cloud storage outage of November 2014.
