aselimc Infrastructure as Code
Terraform Module Pattern
module "vpc" {
source = "./modules/vpc"
cidr = var.vpc_cidr
azs = var.availability_zones
}
State Management
- Remote backend (S3 + DynamoDB lock, GCS, Terraform Cloud)
- One state file per environment (dev/staging/prod)
- Never edit state manually
Environment Separation
- Workspaces OR separate directories per environment
- Share modules, vary variables
- Identical infra across environments (no snowflakes)
ML Infrastructure
- GPU instances:
p3.2xlarge(V100),p4d.24xlarge(A100),p5.48xlarge(H100) - Spot instances for training (with checkpointing)
- S3/GCS for artifact storage
- VPC with private subnets for training clusters
