#12: Optimizing for Sustainability
Tech thought leader and host of the Kubernetes Unpacked podcast Kristina Devochko joins nCast today to talk all things cloud cost optimization, Kubernetes and green tech.
We start by talking about the fact that many companies aren’t even using HALF of their compute resources. But does slashing your AWS bill necessarily mean that you’re saving the plant? We delve into cost optimization and how it aligns (or not) with sustainability.
Kristina shares her insights on measuring your cloud carbon footprint and the tools you need (KEDA, Karpenter, Kepler) to increase cloud sustainability. We discuss key practical ways to get started cutting unnecessary cloud waste, from eliminating orphaned resources to scheduling during off hours.
Plus, we're revealing how nOps has managed to run our production on Spot instances — talk about recycling!
