Aflevering 142: Kubernetes 1.37 Garhwal

Jan constateert dat Kubernetes al een tijd steeds stabieler wordt en dat breaking changes zeldzamer worden. Goed nieuws, al maakt het de zoektocht naar een spannend verhaal voor een release-aflevering er niet makkelijker op. Deze keer valt er genoeg uit te diepen.

Helm 4 is a story about restraint. Helm has become load bearing for an enormous number of enterprises, and a strict versioning policy left technical debt with nowhere to go. Helm 4 clears that debt without breaking anyone.

Traditional VPNs grant broad network access once a user authenticates, creating large lateral movement risk with little to no granular control or auditing. Instead of trusting users based on network location, every connection is signed and validated against intent, who is accessing what, and why.

Kubernetes-platformen worden uitgerold en beheerd over virtualisatielagen, bare metal en de cloud heen. Eric heeft een lange geschiedenis die teruggaat tot de vroege vCenter-tijd, via de opkomst van container orchestration (Mesos, Docker Swarm)

In their KubeCon talk "No Shame in Just Paying," they shared how they tackled this consolidation project: migrating all workloads to three standardized, fully managed Kubernetes distributions.

DB tune focuses entirely on Postgres and deploys a narrow, production-safe AI agent that reads performance metrics and iteratively adjusts server parameters (GUCs) until the system converges on an optimal configuration.

vLLM serves as a "Rosetta Stone" between the ever-growing zoo of models (Llama, DeepSeek, Mistral, Qwen, Nvidia Nemotron) and accelerators (Nvidia, AMD, Intel, Google TPUs).

Mohamed and Thierry discuss why OpenStack is still highly relevant at massive scale, especially for organizations requiring multi-tenancy, hardware abstraction, GPU enablement, HPC workloads, and advanced networking performance.

Carl shares how edge computing has matured. What used to require explaining the concept itself has now shifted toward real-world adoption, with use cases across retail, manufacturing, telecom and beyond.
