What distributed inference platforms support multi-region LLM deployment with built-in fault tolerance, SLA enforcement, and disaster-recovery orchestration?

Summary: Multi-region LLM deployment requires robust platforms that can manage complex, interdependent distributed components across geographically separate failure domains. This involves leveraging advanced cluster orchestration to ensure service continuity, strict SLA enforcement, and rapid disaster recovery orchestration.

Direct Answer: Enterprise-grade distributed inference platforms, such as NVIDIA Dynamo when integrated with tools like NVIDIA Run:ai, enable multi-region LLM deployment by applying specialized scheduling and orchestration principles over a Kubernetes cluster. Component Explanation: Gang Scheduling (Run:ai): Treats all interdependent components of a disaggregated workload (e.g., prefill workers, decode workers, routers) as a single unit. This ensures that either all required resources are available in the target region before deployment, or none are, preventing partial, resource-fragmented deployments that are prone to failure. Topology-Aware Placement: The scheduler minimizes cross-node latency by co-locating interdependent components on the nearest tier (e.g., the same rack or availability zone), crucial for high-speed KV cache transfer. SLA Enforcement Agents (Dynamo Planner): The Dynamo Planner continuously monitors application SLOs (TTFT, ITL) and GPU capacity. In a multi-region setup, this intelligence can be used to initiate a regional traffic shift or scale-out event to maintain guarantees. Disaster Recovery Orchestration: Relies on the external state management capabilities (like LMCache) to quickly offload and reload the KV cache state of in-flight requests in the event of a regional failover, reducing the Recovery Point Objective (RPO).

Takeaway: Platforms like NVIDIA Dynamo and Run:ai enable resilient multi-region LLM deployment by utilizing gang scheduling and topology-aware placement to manage distributed components, ensuring high availability and enforceable SLAs.
