Pricing Analysis

Pricing Overview

AWS employs per-second billing for EC2 GPU instances (e.g., p5.48xlarge with 8 H100s), enabling precise cost control for variable workloads. Spot instances offer up to 90% discounts for interruptible jobs, with Savings Plans/Reserved Instances for 30-70% off committed usage. However, add-ons like data transfer (egress ~$0.09/GB) and complex tiering inflate totals. Voltage Park uses per-hour billing, simpler for long runs but penalizing short experiments (minimum 1-hour charge). No confirmed spot/reserved options, suggesting on-demand focus. Implications: AWS favors bursty, experimental, or spot-eligible workloads (e.g., <1hr jobs save 50%+ vs hourly); Voltage suits sustained, multi-day training where per-hour predictability aids budgeting, but lacks flexibility for intermittent use.

Value Assessment

For small experiments/fine-tuning (<10 GPUs, hours-days), AWS spot instances deliver superior value via per-second granularity and SageMaker integration, often 2-3x cheaper than Voltage's hourly minimum. Large training runs (100s+ H100s, weeks) favor Voltage Park's specialized fleet, potentially lower effective $/GPU-hour due to scale efficiencies (unconfirmed rates, but non-profit model implies competitiveness). Production batch inference leans AWS for cost-optimized Trainium/Inferentia and global edge caching. Real-time inference suits AWS's auto-scaling Lambda/EC2 with low-latency networking. Overall, AWS wins versatility (spot for 70% workloads); Voltage for H100 hyperscale (20-30% savings on massive jobs), assuming equivalent list pricing—evaluate via trials.

Use Case Comparison

LLM Training

Voltage Park recommended

AWS

AWS supports large-scale training via p5 instances (H100s) and Trainium clusters (up to 1000s chips), with SageMaker for managed orchestration, checkpointing to S3, and fault-tolerant scaling. Global AZs ensure redundancy, but costs escalate for 1000+ GPU jobs without custom silicon savings.

Voltage Park

Voltage Park's 24k H100 fleet excels here, enabling rapid provisioning of massive clusters for multi-week runs with high interconnect density. Non-profit backing suggests cost advantages, though limited details on software stack or fault tolerance.

Batch Inference

AWS recommended

AWS

AWS shines with Inferentia/Trainium for cost-efficient batch jobs, SageMaker Batch Transform for serverless scaling, and seamless S3 integration. Spot instances optimize irregular volumes, supporting diverse models beyond H100s.

Voltage Park

Voltage's H100 focus suits high-throughput H100-optimized inference, but per-hour billing and unclear managed batch tools reduce fit for variable, cost-sensitive workloads; better for sustained high-volume runs.

Real-time Inference

AWS recommended

AWS

AWS dominates with low-latency endpoints via SageMaker, ECS/Fargate, or Lambda; global edge locations, auto-scaling, and Inferentia enable sub-100ms latencies at scale. Integrates with API Gateway for production traffic.

Voltage Park

Limited suitability; H100s viable for compute-heavy serving, but no confirmed managed inference services, global low-latency network, or auto-scaling—per-hour model inefficient for always-on needs.

Fine-tuning & Experimentation

AWS recommended

AWS

Per-second spot instances (g5/p4d) and SageMaker Studio/Jupyter enable cheap, iterative experiments with A/B testing, versioning, and quick spin-up/down. Broad instance variety supports prototyping.

Voltage Park

H100 access good for GPU-intensive tuning, but hourly billing wasteful for short (<1hr) trials; lacks managed notebooks or ecosystem for rapid iteration, per limited info.

Technical Comparison

Infrastructure

AWS uses virtualized EC2 with Nitro hypervisor for GPU isolation, offering Elastic Fabric Adapter (EFA) for low-latency multi-node (up to 1000s GPUs), EBS/EFS storage, EKS Kubernetes, and global regions/AZs. Supports diverse GPUs (H100/A100/T4) plus Trainium/Inferentia. Voltage Park likely emphasizes bare-metal or lightly virtualized H100 clusters for max performance, with a 24k GPU pool focused on training-scale networking (unclear RDMA/InfiniBand details). Storage/K8s support unconfirmed, suggesting Slurm/Kubernetes for job scheduling; no global footprint noted.

Performance

AWS H100 p5 instances deliver strong multi-GPU scaling via NVLink/EFA (e.g., 90% weak scaling to 256 GPUs), with Trainium offering 2x training perf/$ vs H100s per AWS benchmarks. Availability high globally, but queue times during peaks. Voltage's 24k H100 fleet promises unmatched availability for 1000+ node jobs, potentially superior raw FLOPS density and interconnect for massive training (e.g., better all-reduce bandwidth), though real-world benchmarks unavailable. AWS edges in mixed-precision optimization via custom chips; Voltage for pure H100 throughput.
