# ComputeEnvironmentOrder
<a name="API_ComputeEnvironmentOrder"></a>

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.

**Note**  
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.
