GPU-Enabled Kubernetes Clusters
Cloud4Y exposes GPUs to Kubernetes the same way it handles CPU and memory: as schedulable, quota-managed compute. No more treating each GPU server as a snowflake.
- Precise allocation — guaranteed GPU shares per workload, enforced at the scheduler level.
- Native scheduling — K8s places pods on GPU nodes based on resource requests, affinities, and taints.
- Linear scaling — add GPU nodes; the cluster picks them up and schedules against them on the next reconcile loop.
The result: faster time-to-inference, higher GPU utilization, lower TCO.
*Quoted per deployment based on node count, GPU SKU, and support tier.
In practice
- Scheduling, automated.GPU assignment is handled by kube-scheduler with device-plugin awareness. Engineers stop managing placement; they ship models.
- Predictable performance per workload. Each pod receives dedicated GPU memory and compute cores via resource limits. No noisy-neighbor degradation on training or inference jobs.
- Horizontal scaling without re-architecture. New GPU nodes join the cluster and become schedulable immediately. The cluster autoscaler handles capacity expansion under load — no manual rebalancing.
- Throughput where CPUs can't compete.Training, inference, computer vision, large-scale data processing — workloads that take hours on CPU complete in minutes on GPU. Measurable, repeatable speedups across the ML lifecycle.
- Compressed iteration cycles.Experimentation, training, evaluation, and production rollout run on the same substrate. Fewer environment mismatches, faster promotion from notebook to prod.
- Higher GPU utilization, lower TCO. Fractional allocation via NVIDIA MPS and MIG lets multiple pods share a single card with hardware-enforced isolation. Combined with cluster autoscaling, idle GPU time drops sharply — and so does your per-inference cost.
Architecture
GPU nodes are exposed to Kubernetes via vendor device plugins. The control plane treats GPUs as advertised resources, identical in handling to CPU and memory requests.
Auto-discovery — device plugins enumerate GPUs on each node and publish them to the API server. No manual node labeling required..
Health monitoring — continuous GPU state checks with alerting hooks into your observability stack.
Fractional allocation — single-card sharing across pods via NVIDIA MPS (process-level concurrency) or MIG (hardware-partitioned isolation), selectable per workload profile.
Deployment
Built on Container Service Extension (CSE), Cloud4Y clusters ship production-ready:
- Pre-configured runtime — GPU drivers, container toolkit, and Docker/containerd integration installed and version-pinned. No compatibility debugging on day one.
- Configurable node pools — select GPU SKU, memory, and core count to match the workload: training, inference, rendering, or mixed.
- Lifecycle automation — declarative deployment of ML pipelines, inference services, and batch jobs. Standard K8s primitives — Deployments, Jobs, HPA — apply directly.
- Engineering time recovered — Data Scientists work on models; SREs work on platform. Cluster bring-up drops from hours to minutes.
Cloud4Y GPU-enabled Kubernetes clusters are production infrastructure for AI/ML — with the performance, utilization, and operational simplicity to ship faster and spend less doing it.
