      version = "~> 4.0"
    }
    aws-cloud-control = {
      source  = "aws-cloud-control/aws-cloud-control"
      version = "~> 1.0"
    }
  }
}

provider "aws" {
  region = "us-west-2" # Replace with your desired region
}

provider "aws-cloud-control" {
  region = "us-west-2" # Replace with your desired region
}

resource "aws_cloud_control_resource" "batch_compute_environment" {
  type = "AWS::Batch::ComputeEnvironment"
  properties = {
    compute_environment_name = "my-batch-compute-environment"
    type                    = "MANAGED"
    compute_resources       = {
      type                  = "EC2"
      maxv_cpus             = 10
      minv_cpus             = 0

This code snippet shows how to define a job queue associated with the compute environment created in the previous section. The `compute_environment_order` property specifies the compute environment and its priority in the queue.

Advanced Configurations and Optimizations

The AWS Cloud Control provider offers flexibility for more sophisticated AWS Batch configurations. Here are some advanced options to consider:

Using Spot Instances for Cost Savings

By utilizing spot instances within your compute environment, you can significantly reduce costs. Modify the `compute_resources` block in the compute environment definition to include spot instance settings.

Implementing Resource Tagging

Implement resource tagging for better organization and cost allocation. Add a `tags` block to both the compute environment and job queue resources in your Terraform configuration.

Automated Scaling

Configure auto-scaling to dynamically adjust the number of EC2 instances based on demand. This ensures optimal resource utilization and cost-efficiency. AWS Batch’s built-in auto-scaling features can be integrated with the AWS Cloud Control provider for a fully automated solution.
