==================================================================================================== TECHNICAL DEEP DIVE: MULTI-NODE TRAINING & NETWORKING ==================================================================================================== ### NVLink vs InfiniBand: Critical for Distributed Training For training LLMs beyond 7B parameters, GPU-to-GPU communication becomes the bottleneck. Modern distributed training requires high-bandwidth, low-latency interconnects. Technology Bandwidth Latency Scope NVLink 4.0 (H100) 900 GB/s ~1 μs Intra-node (same server) InfiniBand NDR 400 Gb/s (50 GB/s) ~1 μs Inter-node (multi-server) Ethernet 100GbE 12.5 GB/s 10-100 μs Standard networking PCIe 5.0 128 GB/s ~0.1 μs GPU to CPU/memory **Key Insight:** For 32+ GPU training, InfiniBand reduces training time by 3-5x vs standard Ethernet. ### Provider Networking Capabilities Provider NVLink InfiniBand Multi-Node Training Best Use AWS ✓ ✗ Limited Single-node Google Cloud ✓ ✗ Limited Single-node Microsoft Azure ✓ ✓ ✓ Distributed Lambda Labs ✓ ✓ ✓ Distributed CoreWeave ✓ ✓ ✓ Distributed Vast.ai ✗ ✗ Limited Single-node RunPod ✓ ✓ ✓ Distributed Paperspace ✗ ✗ Limited Single-node Together AI ✓ ✓ ✓ Distributed Modal ✗ ✗ Limited Single-node Crusoe ✓ ✓ ✓ Distributed **Providers with InfiniBand:** Lambda Labs, CoreWeave, Azure (NDm), RunPod, Crusoe, Together AI **Impact:** Required for efficient training of models >70B parameters across multiple nodes. ==================================================================================================== CONTAINER & RUNTIME SUPPORT ==================================================================================================== **Container Runtime Support:** • AWS Docker, EKS, SageMaker • Google Cloud Docker, GKE, Vertex AI • Microsoft Azure Docker, AKS, Azure ML • Lambda Labs Docker, Pre-configured environments • CoreWeave Kubernetes-native, Docker • Vast.ai Docker (user-provided images) • RunPod Docker-first, Templates • Paperspace Docker, Gradient notebooks • Together AI Managed (API-based) • Modal Python SDK (auto-containerization) • Crusoe Docker, Kubernetes **Framework Support (All providers):** PyTorch, TensorFlow, JAX, Hugging Face Transformers **Distributed Training:** NCCL, DeepSpeed, Megatron, Ray, Horovod ==================================================================================================== PRICE-TO-PERFORMANCE RANKINGS ==================================================================================================== ### H100 Price-Performance Ranking (Higher = Better Value) Rank Provider H100 Price Training Score Inference Score Price-Performance 1 Crusoe $2.00/hr 10 10 50.00 2 CoreWeave $2.40/hr 10 8 37.50 3 Lambda Labs $2.49/hr 10 7 34.14 4 RunPod $2.79/hr 9 10 34.05 5 Vast.ai $1.77/hr 6 5 31.07 6 Modal $3.20/hr 7 10 26.56 7 Google Cloud $6.88/hr 8 9 12.35 8 AWS $6.88/hr 8 9 12.35 9 Paperspace $5.95/hr 6 7 10.92 10 Microsoft Azure $7.35/hr 8 8 10.88 **Winner:** Vast.ai offers best price-performance, but with reliability tradeoffs. **Enterprise Winner:** Lambda Labs balances price, performance, and reliability. ==================================================================================================== RELIABILITY & SLA RANKINGS ==================================================================================================== Provider SLA % Reliability Score Region Count Support Score AWS 99.99 10 30 9 Google Cloud 99.95 9 35 8 Microsoft Azure 99.95 9 60 9 CoreWeave 99.90 9 8 8 Together AI 99.90 9 10 8 Crusoe 99.90 9 4 9 RunPod 99.50 8 9 7 Modal 99.50 8 5 8 Lambda Labs 99.50 7 2 8 Paperspace 99.00 7 5 7 Vast.ai 0.00 5 50 4 **Key Insight:** AWS, Google Cloud, and Azure dominate reliability, but specialized providers like CoreWeave and Together AI offer competitive 99.9% SLAs.
==================================================================================================== FINAL RECOMMENDATIONS BY USER SEGMENT ==================================================================================================== ### Solo Builders & Indie Hackers **Primary Recommendation:** RunPod **Alternative:** Modal **Budget Option:** Vast.ai **Why:** • Per-second billing eliminates waste • Easy Docker-based deployment • Serverless options for bursty inference • Low barrier to entry • Community support and templates **Estimated Monthly Cost:** $100-500/month for typical experimentation ### Early-Stage Startups (Pre-Seed to Series A) **Primary Recommendation:** Lambda Labs **Alternative:** CoreWeave **Budget Option:** RunPod **Why:** • Zero egress fees save $$ during iteration • Pre-configured ML environments reduce DevOps • Academic pricing if applicable (50% off) • InfiniBand for serious training • Predictable pricing **Estimated Monthly Cost:** $2,000-10,000/month for fine-tuning and development ### Scaling Companies (Series B+) **Primary Recommendation:** CoreWeave **Alternative:** Together AI **Budget Option:** AWS (with spot) **Why:** • Kubernetes-native scaling (1 to 1000+ GPUs) • InfiniBand for distributed training • Latest hardware (B200, H200) • Enterprise SLA (99.9%) • Reserved capacity options **Estimated Monthly Cost:** $50,000-500,000/month for production workloads ### Enterprise AI Teams **Primary Recommendation:** AWS **Alternative:** Microsoft Azure **Specialized Use:** Together AI (inference) **Why:** • 99.99% SLA and global redundancy • Compliance certifications (HIPAA, SOC2, FedRAMP) • Deep ecosystem integration • Hybrid cloud capabilities • Enterprise support (24/7) **Estimated Monthly Cost:** $100,000-1M+/month for mission-critical AI ### Research Labs & Academia **Primary Recommendation:** Lambda Labs **Alternative:** Google Cloud **Budget Option:** Vast.ai **Why:** • 50% academic discount (Lambda) • Pre-configured research environments • TPU access (Google) • Publication-ready infrastructure • Flexible resource allocation **Estimated Monthly Cost:** Varies widely; Lambda academic pricing is key ### Inference-Heavy Applications **Primary Recommendation:** Together AI **Alternative:** RunPod Serverless **Budget Option:** Modal **Why:** • OpenAI-compatible APIs • Auto-scaling from 0 • Pay-per-token pricing • Managed endpoints (no DevOps) • Latest hardware (GB200) **Estimated Monthly Cost:** Variable; depends on request volume ==================================================================================================== FINAL DECISION MATRIX ==================================================================================================== If You Need...

Providers without it are only suitable for single-node workloads. 3. **Serverless is Real:** Modal and RunPod Serverless offer <1s cold starts, making pay-per-use viable for production. No more paying for idle GPUs. 4. **Egress Fees Matter:** Lambda Labs' zero-egress policy can save $10,000s during model iteration. Always calculate total cost including data transfer. 5. **Multi-Cloud is Optimal:** Don't pick one provider. Use Lambda/CoreWeave for training, Together AI/Modal for inference, and keep AWS/GCP as enterprise backup. ⚠️ **Common Pitfalls to Avoid:** • Don't assume hyperscaler = better. Specialized providers often outperform on AI workloads. • Don't ignore networking. 100GbE vs InfiniBand makes 3-5x difference in training time. • Don't over-provision. Start small, scale up. RunPod/Modal's per-second billing helps. • Don't lock into one vendor. Multi-cloud GPU strategy gives pricing leverage. • Don't forget spot/preemptible. AWS spot can offer 90% discounts for fault-tolerant workloads. ==================================================================================================== ✅ **FINAL VERDICT** For most AI startups training LLMs in 2025, we recommend: 1️⃣ **Training:** Lambda Labs (zero egress, InfiniBand, great pricing) 2️⃣ **Inference:** Together AI (managed, latest hardware, OpenAI-compatible) 3️⃣ **Experimentation:** RunPod (per-second billing, Docker-friendly, flexible) 4️⃣ **Enterprise Backup:** AWS (reliability, compliance, global scale) This multi-cloud approach balances cost, performance, reliability, and developer experience. ====================================================================================================
