#046 - Simulating, Scheduling, and Saving: Optimizing Kubernetes with David Morrison (Applied Research)
In this episode, Itiel has an insightful conversation with Dr. David Morrison, a research scientist and founder specializing in Kubernetes scheduling and autoscaling. David shares his journey from operations research to leading distributed systems efforts at tech giants like Yelp and Airbnb. Learn about the transition from Apache Mesos to Kubernetes at Yelp, including the role of their open-source API layer, Pasta.
Discover why David started his own venture, Applied Computing Research Labs, to help companies tackle the challenges of Kubernetes cost optimization and reliability. Get an inside look at SimCube, his fascinating project that simulates production Kubernetes clusters for debugging, troubleshooting, and capacity planning.
David also offers insights into the common pitfalls of low cluster utilization, the complexities of saving costs beyond low-hanging fruit, and the potential future of distributed systems.
Join Itiel as he chats with Gianluca Mardente, a Principal Engineer at Cisco Systems. Gianluca shares his path to tech and Kubernetes, including his work history and the inspiration behind his open-source project, Sveltos. They dive into the significant challenges of managing a large fleet of Kubernetes clusters – ensuring consistency, handling upgrades, and coordinating resources across different clusters.
Learn how Gianluca's project tackles these 'Day-2 Operations', offering solutions that go beyond simple cluster creation and enable seamless integration of various open-source tools like Crossplane.

#043 - Gaming on K8s: Stateful Servers, Low Latency, and an Incredible Infra Journey with Siddharth Dhulipalla (Hathora.dev)
In this episode, Sid, CEO of Hathora, discusses building game infrastructure, specifically for hosting dedicated servers. He shares how Hathora tackles the challenges of running stateful, low-latency, high-throughput workloads that reconcile player actions up to 60 times per second. Sid explains their approach using Kubernetes to manage compute across bare metal and cloud VMs, leveraging technologies like Talos and Civo's Omni. He also details the technical hurdles they face with Kubernetes networking (like hostport issues), achieving sub-3-second pod startup times, and optimizing container image pulls, offering insights into the unique demands of the gaming industry and Hathora's growth.
Sid is the CEO and co-founder of Hathora, the premier tool for studios to globally scale dedicated servers for their multiplayer video games. Sid comes from a deeply technical background, having led infra teams responsible for $100m+ annual cloud budgets. His team at Hathora is working with some of the most anticipated games of '25 and beyond, including Frost Giant’s Stormgate, Omeda’s Predecessor, and 1047 Games’ Splitgate 2.

#042 - Cloud-Native Evolution: Simplifying K8s for Developers with Maxime Veroone (Decathlon)
Live from KubeCon London, this episode of Kubernetes for Humans features Maxime Veroone, Staff Engineer at Decathlon's e-commerce division, sharing the company’s cloud-native transformation story.
From their early days running a container platform with Rancher 1 to their strategic move to Kubernetes, Decathlon has embraced modern infrastructure to enable scalability and resilience. But with over 5,000 digital team members, Kubernetes introduced a new challenge: developer experience. As engineers were increasingly expected to navigate complex YAML configurations and act as operators, the need for simplification became critical.
Maxime discusses how his role focuses on bridging the gap between platform and application teams, working to abstract Kubernetes complexity without locking developers into rigid workflows. His approach is rooted in empathy, actively listening to developers and shaping solutions around their needs.
The conversation also dives into Decathlon’s infrastructure practices using Terraform and CI/CD pipelines, and Maxim’s enthusiasm for tools like Flagger and Flux, which are helping ensure safe, progressive deployments in their high-stakes e-commerce environment.
