# ComputeEnvironmentOrderProperty

The order that compute environments are tried in for job placement within a queue.

Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower order integer value is tried for job placement first. Compute environments must be in the `VALID` state before you can associate them with a job queue. All of the compute environments must be either EC2 ( `EC2` or `SPOT` ) or Fargate ( `FARGATE` or `FARGATE_SPOT` ); Amazon EC2 and Fargate compute environments can't be mixed.

> All compute environments that are associated with a job queue must share the same architecture. AWS Batch doesn't support mixing compute environment architecture types in a single job queue.

## Example

```ts
// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_batch as batch } from 'aws-cdk-lib';
const computeEnvironmentOrderProperty: batch.CfnJobQueue.ComputeEnvironmentOrderProperty = {
  computeEnvironment: 'computeEnvironment',
  order: 123,
};
```

## Properties

- `computeEnvironment`: string (required) — The Amazon Resource Name (ARN) of the compute environment.

- `order`: number (required) — The order of the compute environment.

  Compute environments are tried in ascending order. For example, if two compute environments are associated with a job queue, the compute environment with a lower `order` integer value is tried for job placement first.
