Summary of NVIDIA’s Microservices Strategy 🚀
Discover how NVIDIA has devised an innovative strategy for horizontally autoscaling its NIM microservices on Kubernetes utilizing custom metrics. This year, you can delve into a comprehensive resource management method that enhances efficiency and optimizes performance in large-scale machine learning applications.
Overview of NIM Microservices by NVIDIA
NVIDIA’s NIM microservices function as model inference containers that can be deployed within Kubernetes environments. These microservices play a significant role in managing extensive machine learning models. A thorough understanding of their compute and memory characteristics in a production setting is essential for effective autoscaling to take place.
Initiating Autoscaling 🌟
To begin the autoscaling process, you need to establish a Kubernetes cluster with vital components, including the Kubernetes Metrics Server, Prometheus, Prometheus Adapter, and Grafana. These tools are crucial in collecting and displaying metrics essential for the Horizontal Pod Autoscaler (HPA) service.
The Kubernetes Metrics Server is responsible for collecting resource metrics from Kubelets and making them available via the Kubernetes API Server. Meanwhile, Prometheus and Grafana work together to scrape metrics from the pods, while the Prometheus Adapter facilitates the utilization of custom metrics by the HPA for its scaling operations.
Deploying NIM Microservices 🛠️
NVIDIA offers an in-depth guide for the deployment of NIM microservices, with a particular focus on the NIM for LLMs model. This process requires setting up the essential infrastructure and ensuring the readiness of the NIM for LLMs microservice to scale effectively based on GPU cache utilization metrics.
Utilizing Grafana dashboards enables the visualization of these custom metrics, enhancing your ability to monitor and adjust the allocation of resources based on varying traffic and workload requirements. The deployment phase also includes generating traffic using tools such as genai-perf, which is instrumental in evaluating the impact of different concurrency levels on resource use.
Executing Horizontal Pod Autoscaling ⏩
To set up HPA, NVIDIA showcases the process of creating an HPA resource that focuses on the gpu_cache_usage_perc metric. By executing load tests at various levels of concurrency, the HPA automatically modifies the number of pods to ensure optimal performance, effectively managing workloads that fluctuate.
Exploring Future Possibilities 🌈
NVIDIA’s current approach paves the way for further advancements, such as scaling based on a variety of metrics like request latency or GPU compute usage. Moreover, employing Prometheus Query Language (PromQL) to generate new metrics can significantly improve the autoscaling functionalities available.
