DR: Staying resilient in the cloud

About this episode

The episode discusses the misconceptions of cloud resilience and the shared responsibility model with guest Seth Eliot from Arpio.

Share Episode                     Welcome back to another hopefully, relief from architectural existential dread. This week, we've pulled in Seth Eliot from Arpio , (Ar-Pi-O, RPO, get it?), to dive headfirst into the beautiful, deeply expensive illusion that migrating your legacy infrastructure to a major hyperscaler magically grants it instant immortality. It doesn't . We break down the shared responsibility model for resilience, which was conveniently cribbed straight from the security model, and analyze how the foundational promise of automated fault isolation boundaries routinely crumbles.           From cloud providers sticking multiple "independent" availability zones inside the exact same physical building, to multi-AZ cascading anomalies, to regional power grid failures, it's clear your provider's abstractions aren't nearly as resilient as their marketing slides suggest.           Discussed within is the "Thundering Herd" phenomenon, that can't be ignored even when the failover clusters are…
