David Pech | The Gems of Kubernetes' Latest Features TechMeetup Ostrava Conference 2025 | DevOps & System Stage 7.11.2025 ==== Kubernetes is a de facto standard for container orchestration, yet it quietly evolves, often unnoticed by those who rely on it every day. This talk shines a spotlight on impactful features introduced in recent releases that can dramatically transform how you run containers—especially for stateful workloads (databases) and machine learning. We’ll explore Dynamic Resource Allocation (DRA), which lets you allocate special HW, online Pod resizing, enabling you to modify CPU and memory settings on the fly without restarting Pods. We’ll also dive into SWAP support, which offers a more flexible way to handle temporary memory spikes and improve performance under heavy startup loads. ImageVolumes can reduce image duplication across your cluster, saving both storage space and network overhead. VolumeSnapshots and GroupVolumeSnapshots simplify backup and restore processes across multiple volumes, making data management far more efficient. Pod-level resource allocation provides granular control by setting resource constraints on a per-pod basis, ensuring fair usage and easier troubleshooting. And the list goes on. With practical examples, you’ll leave with a deeper understanding of these cutting-edge Kubernetes capabilities. So you can start leveraging these new concepts and maybe try to bring yet another workloads to Kubernetes in the future.
