EP166 Workload Identity, Zero Trust and SPIFFE (Also Turtles!‪)‬ Cloud Security Podcast by Google

Guests:
Evan Gilman, co-founder CEO of Spirl
Eli Nesterov, co-founder CTO of Spril
Topics:
Today we have IAM,  zero trust and security made easy. With that intro, could you give us the 30 second version of what a workload identity is and why people need them? 
What’s so spiffy about SPIFFE anyway? 
What’s different between this and micro segmentation of your network–why is one better or worse? 
You call your book “solving the bottom turtle” could you tell us what that means?
What are the challenges you’re seeing large organizations run into when adopting this approach at scale? 
Of all the things a CISO could prioritize, why should this one get added to the list? What makes this, which is so core to our internal security model–ripe for the outside world?
How people do it now, what gets thrown away when you deploy SPIFFE? Are there alternative?
SPIFFE is interesting, yet can a startup really “solve for the bottom turtle”?
