SkyServe: Serving AI Models across Regions and Clouds with Spot Instances
SkyServe introduces SpotHedge, an innovative policy that leverages spot instances across multiple regions and clouds to significantly reduce the cost of AI model serving while maintaining high availability and improving latency. By dynamically managing a mixture of spot and on-demand replicas, over-provisioning for resilience, and intelligent placement, SkyServe addresses the key challenges of spot instance volatility and preemption.

Average Cost Reduction with SkyServe vs. On-Demand
SkyServe achieves substantial cost savings by intelligently provisioning cheaper spot instances across diverse cloud regions, dynamically falling back to on-demand instances only when necessary due to preemption or unavailability. This adaptive approach avoids the fixed overhead of always-on, expensive on-demand replicas.

SkyServe addresses the challenge of correlated spot GPU preemptions by spreading replicas across wider failure domains (regions and clouds). This diversification ensures that service disruptions are minimized, even when local spot resources become temporarily unavailable. The system's dynamic fallback mechanism ensures that on-demand replicas are swiftly provisioned when spot resources are insufficient, guaranteeing continuous service availability.

Enterprise Scenario: LLM Deployment
A large enterprise faced exorbitant costs hosting a Llama-2-70B model for customer support. Traditional methods resulted in frequent service disruptions due to spot instance preemptions, or excessive costs with on-demand. By adopting SkyServe, they achieved a 40% reduction in monthly cloud spend while improving their API's P90 latency by 2.0x, ensuring consistent, high-quality service even during peak loads and GPU shortages across regions. This allowed them to scale their AI operations globally without financial strain or reliability concerns.
