Service Selection Criteria

Multi-Account Setup

# AWS Organizations
resource "aws_organizations_organization" "main" {
  feature_set: "ALL"
}

resource "aws_organizations_organizational_unit" "production" {
  name      = "Production"
  parent_id = aws_organizations_organization.main.roots[0].id
}

resource "aws_organizations_account" "prod-network" {
  name  = "prod-network"
  email = "network@company.com"
  parent_id = aws_organizations_organizational_unit.production.id
}

resource "aws_organizations_account" "prod workloads" {
  name  = "prod-workloads"
  email = "workloads@company.com"
  parent_id = aws_organizations_organizational_unit.production.id
}
