Introducing multi-cluster GKE Inference Gateway: Scale AI workloads globally
Google Cloud announces the preview of multi-cluster GKE Inference Gateway to enhance scalability, resilience, and efficiency of AI/ML inference workloads across multiple GKE clusters and regions.
Why it matters
This solution helps scale AI/ML inference workloads globally with improved reliability, efficiency, and simplified operations.
Key Points
- 1Addresses limitations of single-cluster deployments like availability risks, scalability caps, resource silos, and high latency
- 2Provides enhanced high reliability and fault tolerance by intelligently routing traffic across multiple GKE clusters and regions
- 3Improves scalability and optimizes resource usage by pooling and leveraging GPU/TPU resources from various clusters
- 4Offers globally optimized, model-aware routing using advanced signals like real-time custom metrics
Details
The multi-cluster GKE Inference Gateway leverages the power of multi-cluster Gateways to provide intelligent, model-aware load balancing for demanding AI applications. It addresses challenges like regional outages, hardware limits, underutilized accelerators, and high latency by enabling traffic routing across multiple GKE clusters, even in different regions. This provides enhanced reliability, scalability, and efficient resource usage. The Inference Gateway can make smart routing decisions using real-time custom metrics like model server's KV cache utilization to send requests to the best-equipped backend instance. It also simplifies operations by allowing management of a globally distributed AI service through a single Inference Gateway configuration.
