#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. Chapters: 0:00 - 2:20: Haoran Chu and the state of cloud resource management 2:20-6:00: Historical evolution of autoscaling 6:01 - 10:45: HPA, VPA and Multidimensional Autoscaling 10:46 - 18:50: Challenges of MPA: heuristics versus machine learning 18:51 - 24:20: How to quantify excess capacity? 24:21 - 32:16: The state of ML in autoscaling 32:16 - 37:37: Operationalizing ML in production environments37:37 - 42:01: The near-term future of autoscaling

#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

#10: FinOps 101 with the AWS Optics team (Part 1): Automating Governance

Today we’re joined by Savanna Jensen, Senior FinOps Success Manager on the Optics Team at AWS, to discuss how to implement a Cloud FinOps automation strategy. The less amount of “people time” you can dedicate to cloud management and the more automation you can bake into the system, the easier it will be — but what are the right tools to use? We start out by tapping Savanna’s insider knowledge on the latest and greatest AWS Cost Management tools. Get the latest on the shiny new updates to Cost Explorer that just launched. Plus, pro tips on the best filters and features to use for various use cases when it comes to the Cost and Usage Report (CUR), Cost Explorer, and QuickSight. We dive into Engineering vs. FinOps perspectives and frustrations. How can you orchestrate a culture where cost optimization feels motivating rather than punitive to Engineers (recognition, career rewards, gamification…)? How do you troubleshoot if you’re a FinOps leader seeing zero traction on your initiatives? Hear real-world battle stories about organizations tackling cost management challenges — and the takeaways for achieving true visibility and control over cloud costs. And stay tuned next week for Part 2 with the AWS Optics team.

#7 - My Baby Is Not Ugly! FinOps X, Public Sector Cloud, & AWS Billing Horror Stories

We’re thrilled to host Marit Hughes, a Specialist Master for Government and Public Sector at Deloitte. After debating the best FinOps conferences to attend this year, we tackle the question: with billions and billions of dollars being spent on cloud resources, why is it so hard to make cost optimization actually happen? And as we navigate the unique maze of public sector cloud optimization, get the inside scoop on why it's a different beast from commercial and the conversations taking place behind the scenes. We discuss the realities of engineering life in the trenches — from lack of tooling and visibility to 18-hour days flooded by JIRA tickets. (Plus, bonkers things we’ve seen in bills). Whether you’re in public sector or private, how do you make cost management a lot less painful for engineers? The other side of the question is where and how FinOps practitioners should insert themselves to execute and achieve quantifiable results. (Hint: telling engineers their baby is ugly isn’t going to help). Marit reveals the secret sauce for turning defensive conversations into collaborative ones — find out how to unruffle feathers, bridge Engineering and Finance, and deflect the default reaction of “I can’t do that”.
