Episode 1: Cost Per Streaming Hour: Roku's FinOps Playbook (Dieter Matzion)

On episode 1 of ShiftLeft FinOps, host Mike Weider talks with Dieter Matzion, who works on Roku's cloud and technology infrastructure team supporting FinOps and previously held senior engineering roles at Intuit, Netflix, and Google. They cover how Roku holds their cost per streaming hour number flat, why a new feature has to be funded by an optimization found elsewhere first (Dieter compares it to carbon credit trading), and why a pure cost anomaly (a single S3 storage class transition that ran into the tens of thousands of dollars) is a different problem than a KPI-moving rollout. They also get into FinOps versus Tokenomics: why value-per-dollar and value-per-token turn out to need completely different skills, what a healthy cache hit ratio looks like (around 80%), and why Roku's top 25 engineers already account for 16% of all AI spend.
