availability_zones | Patterned Designs Documentation

Type list(string)

Module vpc

List of availability zones for subnet distribution

Availability Zone Selection

Use the aws_availability_zones data source for dynamic selection:

data "aws_availability_zones" "available" {
  state = "available"
}

Best Practices

Use at least 2 AZs for high availability
Use 3 AZs for production workloads
Verify AZ availability in your region
