#14: How Sonos Mastered Spot: Karpenter GA, KubeCon & More
<p>Karpenter has achieved GA and is disrupted the autoscaling game, with data pointing to accelerated adoption. </p> <p>Today, Josh Cypher, DevOps leader at Sonos, joins us to talk about some unexpected byproducts of adopting Karpenter at Sonos. Josh dives into his favorite features and efficiency gains, from node consolidation to better disruption controls.</p> <p>The public cloud bill is a massive operational expense for tech organizations, yet tracking the success of optimization efforts often frustrates engineers. Josh and James explore these challenges and how to address them effectively.</p> <p>As big-time Spot adopters, Sonos has unlocked impressive savings (50%?!) by focusing on high-impact, low-overhead strategies. Josh explains how visibility brought them quick wins and paved the way for further optimization across Sonos’s infrastructure.</p> <p>Plus, Josh and James preview what they’re looking forward to at KubeCon, including key conversations on Kubernetes, AI, and cloud sustainability.</p>

#13: Multidimensional Pod Autoscaling & Machine Learning for Cloud Optimization
<p>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. </p> <p>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.</p> <p>But is MPA poised to redefine resource optimization? What problems does it solve, and what fresh complexities are involved in its implementation?</p> <p>Haoran and James dig into these questions while debating traditional heuristic versus Machine Learning approaches, industry versus academia, and other hot topics in Kubernetes.</p> <p>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.</p> <p>Chapters:</p> <p>0:00 - 2:20: <strong>Horan Chu and the state of cloud resource management</strong></p> <p>2:20-6:00: <strong>Historical evolution of autoscaling</strong></p> <p>6:01 - 10:45: <strong>HPA, VPA and Multidimensional Autoscaling</strong></p> <p>10:46 - 18:50: <strong>Challenges of MPA: heuristics versus machine learning</strong></p> <p>18:51 - 24:20: <strong>How to quantify excess capacity?</strong></p> <p>24:21 - 32:16: <strong>The state of ML in autoscaling</strong></p> <p>32:16 - 37:37: <strong>Operationalizing ML in production environments</strong><br>37:37 - 42:01: <strong>The near-term future of autoscaling</strong></p>

#12: Optimizing for Sustainability
<p>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. </p> <p>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. </p> <p>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. </p> <p>Plus, we're revealing how nOps has managed to run our production on Spot instances — talk about recycling! </p> <p>0:00 - 1:09: Introduction</p> <p>1:10 - 4:20: Sustainability at Kubecon Europe and other recent events</p> <p>4:21 - 9:31: Is cost optimization the same as sustainability?</p> <p>9:32 - 12:53: Green data centers and your carbon footprint</p> <p>12:54 - 15:21: Portability and the downsides of over-committing to pricing plans</p> <p>15:22 - 19:51: Measuring your organization’s cloud sustainability</p> <p>19:53 - 26:51: KEDA, Karpenter, Kepler and the tools you need</p> <p>26:52 - 31:12: Leveraging available Spot capacity and choosing instances</p> <p>31:13 - 37:15: Running production environments on Spot </p> <p>37:15 - 44:46: Continual rightsizing and automated tools</p> <p>44:47 - 48:18: Carbon-efficient Karpenter scaling</p> <p>Show notes</p> <ul> <li><p><a href="https://github.com/aws/karpenter-provider-aws/pull/4686%20and%20https://github.com/kubernetes-sigs/karpenter/issues/675">GitHub issue</a> for proposal of carbon-efficient design to Karpenter that needs some community support</p> </li> <li><p><a href="https://sustainable-computing.io">Kepler</a> project</p> </li> <li><p><a href="https://github.com/Azure/carbon-aware-keda-operator">Carbon-aware KEDA operator</a></p> </li> <li><p><a href="https://www.cloudcarbonfootprint.org">Cloud Carbon Footprint</a> open source tool</p> </li> <li><p><a href="https://github.com/Boavizta/boaviztapi">BoaviztAPI</a> open source API for environmental impacts of ICT</p> </li> <li><p>APIs that provide electricity data, data on carbon emissions and electricity sources: <a href="https://app.electricitymaps.com/">https://app.electricitymaps.com</a> and <a href="https://watttime.org/">https://watttime.org</a></p> </li> <li><p>CNCF <a href="https://tag-env-sustainability.cncf.io">TAG Environmental Sustainability</a></p> </li> <li><p>Contact <a href="https://www.biodrop.io/guidemetothemoon">Kristina Devochko</a></p> </li> <li><p>Kristina Devochko’s <a href="https://www.kristhecodingunicorn.com">Tech blog</a><br></p> </li> </ul>
