Compute Options for AI Workloads Intermediate

AI workloads demand specialized compute resources. Choosing the right instance type, accelerator, and deployment model can mean the difference between a training job that takes hours versus weeks, and an inference endpoint that costs $100/month versus $10,000/month. This lesson covers the full spectrum of compute options available in the cloud.

GPU Instance Families

Provider Instance GPU Best For
AWS p5.48xlarge 8x H100 80GB Large model training, LLM fine-tuning
AWS g5.xlarge 1x A10G 24GB Inference, small model training
GCP a3-highgpu-8g 8x H100 80GB Large-scale training
Azure ND H100 v5 8x H100 80GB HPC and large model training

Custom AI Accelerators

  • Google TPU v5p - Custom tensor processing units optimized for TensorFlow and JAX workloads with high memory bandwidth
  • AWS Trainium - Purpose-built for training with up to 50% cost savings over GPU instances for supported frameworks
  • AWS Inferentia2 - Optimized for inference with high throughput and low latency at reduced cost
  • Azure Maia 100 - Microsoft's custom AI accelerator designed for cloud-scale AI workloads

Serverless Inference Options

For variable or unpredictable inference workloads, serverless options eliminate idle costs:

  • AWS SageMaker Serverless Inference - Pay-per-request model serving with automatic scaling
  • Google Cloud Run - Container-based serverless with GPU support for inference
  • Azure Container Instances - On-demand container execution with GPU support

Choosing the Right Compute

Decision Matrix
Training (Large Models, LLMs):
  GPU: H100, A100 (multi-GPU, multi-node)
  TPU: v5p pods for TensorFlow/JAX
  Custom: Trainium for supported frameworks

Training (Small/Medium Models):
  GPU: A10G, L4, T4
  Spot/Preemptible: 60-90% cost savings

Inference (Real-time, Low Latency):
  GPU: L4, T4, A10G (single GPU)
  Custom: Inferentia2 for throughput
  Serverless: Low-traffic endpoints

Inference (Batch):
  GPU: Any available (spot instances)
  CPU: For small models with batch processing
Cost Tip: Always start with the smallest instance that meets your latency and throughput requirements, then scale up. Over-provisioning GPU resources is one of the most common and expensive mistakes in cloud AI.
