Compare Coreweave AWS Azure Google Cloud for AI GPUs

Choosing a cloud provider for AI workloads is a critical decision that affects cost, performance, and scalability. This guide walks you through comparing Coreweave, AWS, Azure, and Google Cloud for GPU-based AI training and inference, covering pricing, hardware, availability, and key differentiators to help you select the right platform for your needs.

What You’ll Need

• A clear understanding of your AI workload: training vs. inference, model size, and expected usage hours.
• Access to each provider’s public pricing pages (Coreweave, AWS, Azure, Google Cloud) to compare current rates.
• A list of your technical requirements: GPU type (e.g., A100, H100, A10G), number of GPUs, memory, and networking needs.
• Knowledge of your geographic region and data residency requirements.

Step-by-Step

1. Define your workload requirements. Determine whether you need GPUs for training (high compute, large memory) or inference (lower latency, cost-sensitive). Note the exact GPU model you want (e.g., NVIDIA A100, H100, V100, or newer) and the number of GPUs per instance. Also consider your storage and networking needs (e.g., high-bandwidth interconnects for multi-GPU training).
2. Compare GPU availability and types. Check which GPU models each provider offers. Coreweave specializes in NVIDIA GPUs and often has the latest models available sooner than hyperscalers. AWS, Azure, and Google Cloud offer a broad range of GPUs but may have limited availability for the most in-demand models like H100. Look at the specific instance types: AWS P4d/P5, Azure ND-series, Google Cloud A2/A3, and Coreweave’s GPU instances.
3. Evaluate pricing models. Compare on-demand, reserved, and spot/preemptible pricing. Coreweave is known for aggressive pricing on GPU instances, often lower than the big three for equivalent hardware. AWS, Azure, and Google Cloud offer sustained-use discounts, reserved instances, and spot instances that can significantly reduce costs if you have flexible workloads. Use each provider’s pricing calculator to estimate monthly costs for your specific configuration.
4. Check networking and scalability. For distributed training, network bandwidth is crucial. Look for providers offering high-speed interconnects like InfiniBand or high-throughput Ethernet. Coreweave provides NVIDIA Quantum InfiniBand for multi-node training. AWS offers Elastic Fabric Adapter (EFA), Azure has InfiniBand on ND-series, and Google Cloud has Jupiter networking with high bandwidth. Consider how easily you can scale from a single GPU to hundreds.
5. Review software and ecosystem. Each provider has its own AI stack. AWS offers SageMaker, Azure has Azure Machine Learning, Google Cloud has Vertex AI, and Coreweave provides Kubernetes-native services with popular AI tools. Evaluate which platform integrates best with your existing workflows, frameworks (PyTorch, TensorFlow, JAX), and MLOps tools. Also check support for container orchestration (Kubernetes) and serverless options.
6. Assess storage options. AI workloads require fast, scalable storage. Compare object storage (S3, Azure Blob, Google Cloud Storage, Coreweave Storage), file storage (EFS, Azure Files, Filestore, Coreweave Filesystem), and high-performance parallel file systems. Consider data transfer costs and latency, especially if you’re moving large datasets.
7. Evaluate support and SLAs. Check the service level agreements (SLAs) for uptime and support response times. Hyperscalers offer enterprise-grade support with 24/7 availability, while Coreweave provides specialized support for GPU workloads. Consider your team’s expertise and whether you need hands-on assistance.
8. Test with a pilot project. Run a small-scale benchmark or proof-of-concept on each provider to measure real-world performance, startup times, and ease of use. Use a representative model to compare training throughput and inference latency. This will give you concrete data to inform your decision.
9. Consider total cost of ownership (TCO). Beyond raw GPU pricing, factor in egress fees, storage costs, management overhead, and the cost of idle resources. A provider with slightly higher GPU prices might be cheaper overall if it offers better storage and networking options that reduce your total spend.

Common Mistakes

• Ignoring hidden costs: Egress fees, storage costs, and charges for additional services can significantly increase your bill. Always calculate TCO, not just GPU hourly rates.
• Overlooking GPU availability: The most popular GPUs like H100 are often in short supply. Check real-time availability in your region before committing to a provider.
• Underestimating network requirements: For distributed training, network bandwidth is as important as GPU compute. Choosing a provider with slow interconnects can severely bottleneck performance.
• Not considering spot instances: Spot/preemptible instances can save 60-90% but are interruptible. If your workload is fault-tolerant, you can save a lot, but if you need reliability, they may not be suitable.
• Forgetting about data transfer: Moving large datasets to and from the cloud can be slow and expensive. Plan your data ingestion and egress strategy in advance.

Tips

• Use pricing calculators: All four providers offer detailed pricing calculators. Input your exact requirements to get accurate estimates.
• Look for startup credits: Many providers offer free credits for new users (e.g., AWS Free Tier, Azure Free Account, Google Cloud $300 credit). Coreweave may have promotional offers; check their website.
• Monitor your usage: Set up cost alerts and use monitoring tools to track GPU utilization. This helps you avoid overspending on idle resources.
• Consider multi-cloud: You don’t have to choose just one. Use different providers for different workloads to optimize cost and performance.
• Stay updated: GPU pricing and availability change frequently. Re-evaluate your choice periodically to ensure you’re still getting the best deal.

Troubleshooting

• GPU not available: If a specific GPU model is out of stock, try a different region or consider a slightly different model (e.g., A100 instead of H100). Alternatively, use spot instances for non-critical workloads.
• Performance slower than expected: Check network latency and bandwidth between instances. Ensure your training script is optimized for distributed computing. Also verify that you’re using the latest drivers and libraries.
• Costs exceeding budget: Review your usage patterns. Are you leaving instances running when not in use? Use auto-scaling and scheduled shutdowns to reduce waste. Consider moving to spot instances or reserved capacity for predictable workloads.
• Data transfer too slow: Use parallel uploads, or consider using a provider’s data transfer appliance (e.g., AWS Snowball, Azure Data Box) for large initial data loads. Optimize your data pipeline to reduce the amount of data transferred.
• Difficulty with setup: Most providers have detailed documentation and quickstart guides. If you’re stuck, use their support channels, community forums, or consult with a cloud architect.

Frequently Asked Questions

• Is Coreweave cheaper than AWS, Azure, and Google Cloud? Generally, Coreweave offers lower prices for GPU compute, often 30-50% less than hyperscalers for equivalent hardware. However, you need to factor in other costs like storage and networking.
• Which provider has the best GPU availability? Coreweave specializes in GPUs and often has better availability for the latest models. Hyperscalers may have limited stock for popular GPUs, especially during high demand.
• Can I use spot instances for AI training? Yes, all four providers offer spot/preemptible instances. They are ideal for fault-tolerant training jobs that can be paused and resumed. Just be prepared for interruptions.
• Do I need InfiniBand for distributed training? For large-scale training across multiple nodes, high-speed networking like InfiniBand is highly recommended. For single-node training, regular Ethernet is sufficient.
• Which provider is best for Kubernetes-based AI? Coreweave is built on Kubernetes and offers a native experience. Google Cloud (GKE) and Azure (AKS) also have excellent Kubernetes support. AWS EKS is also capable but may require more configuration.
• How do I estimate my total cost? Use each provider’s pricing calculator, input your expected GPU hours, storage, and data transfer. Also, consider the cost of idle resources and management overhead.
