    #13: Multidimensional Pod Autoscaling & Machine Learning for Cloud Optimization

    Dr. Haoran Qiu, a fresh PhD from the University of Illinois Urbana-Champaign, joins our host James Wilson, VP of Engineering at nOps. They’re diving into multidimensional autoscaling, an area in which Haoran’s pioneering research is making waves in the Kubernetes community.  Some workloads work better with Horizontal Pod Autoscaler (HPA), others with Vertical Pod Autoscaler (VPA).  Running them together can create conflicts, but using only one limits efficiency gains. A Multidimensional Pod Autoscaler solves this dilemma by combining the benefits of both VPA and HPA to dynamically adjust both the number and size of pods. But is MPA poised to redefine resource optimization? What problems does it solve, and what fresh complexities are involved in its implementation? Haoran and James dig into these questions while debating traditional heuristic versus Machine Learning approaches, industry versus academia, and other hot topics in Kubernetes. Listen now to discover if MPA is the holy grail of cloud optimization as we discuss the evolution of autoscaling technologies and their impact on cost, sustainability, and developer experience.

    #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!  0:00 - 1:09: Introduction 1:10 - 4:20: Sustainability at Kubecon Europe and other recent events 4:21 - 9:31: Is cost optimization the same as sustainability? 9:32 - 12:53: Green data centers and your carbon footprint 12:54 - 15:21: Portability and the downsides of over-committing to pricing plans 15:22 - 19:51: Measuring your organization’s cloud sustainability 19:53 - 26:51: KEDA, Karpenter, Kepler and the tools you need 26:52 - 31:12: Leveraging available Spot capacity and choosing instances 31:13 - 37:15: Running production environments on Spot  37:15 - 44:46: Continual rightsizing and automated tools 44:47 - 48:18: Carbon-efficient Karpenter scaling Show notes GitHub issue for proposal of carbon-efficient design to Karpenter that needs some community support Kepler project Carbon-aware KEDA operator Cloud Carbon Footprint open source tool BoaviztAPI open source API for environmental impacts of ICT APIs that provide electricity data, data on carbon emissions and electricity sources: https://app.electricitymaps.com and https://watttime.org CNCF TAG Environmental Sustainability Contact Kristina Devochko Kristina Devochko’s Tech blog
