Elevate Your LLM Inference: Autoscaling with Ray, ROCm 7.0.0, and SkyPilot
Summary
This blog post, published on February 13, 2026, details how to autoscale large language model (LLM) inference workloads using Ray Serve with a vLLM backend on AMD Instinct GPUs, leveraging AMD's ROCm 7.0.0 software platform. It demonstrates scaling from single-GPU to multi-cluster deployments, including multi-node and multi-cloud configurations via SkyPilot. The article provides a step-by-step guide for setting up a Docker container with ROCm 7.0.0, installing vLLM 0.10.2 from source, and configuring Ray Serve 2.52.1 for autoscaling on a single node with 8 MI300X GPUs. It further illustrates multi-node and multi-cluster autoscaling using SkyPilot across two Kubernetes clusters, each with a single AMD Instinct MI300X GPU, showcasing how these tools manage variable request loads to optimize performance and control infrastructure costs.
Key takeaway
For AI Engineers and MLOps teams deploying LLM inference, integrating Ray Serve with ROCm 7.0.0 on AMD Instinct GPUs, augmented by SkyPilot for multi-cloud orchestration, offers a robust solution for managing fluctuating traffic. You should configure autoscaling policies carefully to balance performance and cost efficiency, ensuring your infrastructure dynamically adapts to demand without manual intervention. This setup allows for seamless scaling from single-node to complex multi-cluster environments.
Key insights
Ray Serve, ROCm 7.0.0, and SkyPilot enable scalable, cost-efficient LLM inference across diverse cloud and cluster environments.
Principles
- Autoscaling optimizes resource use for variable LLM inference loads.
- Unified platforms simplify scaling from single-GPU to multi-cloud.
- Monitoring metrics drives dynamic replica adjustments.
Method
Configure Ray Serve with vLLM on ROCm-enabled AMD GPUs, setting autoscaling policies like `max_ongoing_requests` and `target_ongoing_requests`. For multi-cluster, use SkyPilot with a YAML configuration to deploy and manage Ray Serve replicas across Kubernetes clusters.
In practice
- Use `rocm/vllm` Docker images for vLLM inference on ROCm 7.0.0.
- Employ Locust for client-side load testing to trigger autoscaling.
- Monitor Ray Dashboard and logs to verify autoscaling behavior.
