In a presentation at today’s MPLS, NFV and SDN World Congress in Paris, he revealed that Google has about 10,000 switches in operation in a typical large data center and is now handling around 30,000 configuration changes every month.

Humans are looking at the design elements but software needs to handle the nitty-gritty.”
Pandey estimates that about 70% of failures happen when a management operation is in progress. The apparent aim is to make improvements through even greater reliance on automation
