Dec 1, 2025December 2025: Delivered major modernization of the Kubernetes-on-AWS cluster and improvements to autoscaling and provisioning. Upgraded the cluster to Kubernetes v1.34.3 with latest kube-proxy, optimized provisioning (zone awareness, exclusion of slow instance types), cleaned unused configurations, and enhanced stack deployment with stackset-controller updates. Upgraded Vertical Pod Autoscaler to v1.5.1, adjusted update mode to Recreate for stability, and refreshed VPA CRDs for scheduled scaling. Fixed a Prometheus VPA manifest issue by correcting the config-item name to ensure proper scheduling events. Result: improved performance, reliability, and resource efficiency, with reduced risk of misconfigured autoscaling and lower ongoing maintenance for dependencies.

Nov 1, 2024Month: 2024-11 – Delivered networking, observability, and control-plane enhancements for zalando-incubator/kubernetes-on-aws with a focus on reliability, IPv6 readiness, and ops efficiency. Key features delivered include Advanced AWS VPC CNI enhancements enabling custom CIDR ranges and dedicated subnets, IPv6 testing and EKS IPv6 support, Prometheus scraping for the EKS control plane, and an optional internal AWS Network Load Balancer for the control plane. Also implemented Kubernetes admission controller stability by excluding eks-pod-identity-agent from webhook processing, and improved governance/test-suite hygiene to reduce flaky tests and keep approvals aligned with the current team.
