Multiple teams within the same company increasingly need shared access to expensive GPU clusters for their generative AI operations, while maintaining isolation boundaries, resource fairness, and operational independence. Consider a data science team training large language models, a computer vision group running inference workloads, and a research team experimenting with new model architectures. All of them might need access to the same cluster. Without a well-designed multi-tenant (multi-team) architecture, organizations face uncontrolled resource consumption, weak isolation between teams, an inability to attribute shared GPU costs to the teams that incur them, and administrative overhead that slows down innovation.

Amazon SageMaker HyperPod is a purpose-built AI service that simplifies the management of large-scale compute clusters for gen AI workloads. It provides resilient, optimized clusters orchestrated by Amazon Elastic Kubernetes Service (Amazon EKS) or Slurm, so organizations can run distributed training, interactive development, and model inference at scale. At the same time, it automatically handles node health monitoring, fault recovery, and cluster lifecycle management.

In this post, we present a reference architecture for building a multi-tenant environment on Amazon SageMaker HyperPod with EKS. This architecture uses AWS IAM Identity Center for centralized authentication, per-team SageMaker AI domains for a tailored user experience, Kubernetes namespaces for workload isolation, HyperPod Task Governance for fair resource allocation, and namespace-level cost allocation for per-team spend visibility and chargeback. By the end of this post, you will have a clear blueprint for multiple teams to efficiently share a single HyperPod EKS cluster.
