   #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.

   #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”.

    #5 - Solving the Cost Puzzle : Showbacks, Visibility and Resource Allocation

    Arnold de Leon joins to talk about cloud economics. The cloud can be great, but only if you embrace elastic — if you’re not actively using a resource, you shouldn’t have it. However, navigating the complexities of cloud costs, from network fees to Savings Plans, is often easier said than done. We'll discuss common pitfalls, epic fails, and how to fix them. And because we love a good plot twist, we’re diving into why engineers should be taking more risks when it comes to cost optimization. Sometimes you have to spend a little to save a lot; opportunity cost is a thing. We dive into the present and future of cost allocation tooling. Showbacks are crucial if you want to match usage to actual spend. But how do you get showbacks across the dimensions that are important to engineering, rather than finance? And: once you have the right insights, how do you get engineers to take action on them? Listen now to find out.
