# AWS FIS experiment template components
<a name="experiment-templates"></a>

You use the following components to construct experiment templates:

**Actions**  
The [AWS FIS actions](fis-actions-reference.md) that you want to run. Actions can be run in a set order that you specify, or they can be run simultaneously. For more information, see [Actions](action-sequence.md).

**Targets**  
The AWS resources on which a specific action is carried out. For more information, see [Targets](targets.md).

**Stop conditions**  
The CloudWatch alarms that define a threshold at which your application performance is not acceptable. If a stop condition is triggered while an experiment is running, AWS FIS stops the experiment. For more information, see [Stop conditions](stop-conditions.md).

**Experiment role**  
An IAM role that grants AWS FIS the permissions required so that it can run experiments on your behalf. For more information, see [Experiment role](getting-started-iam-service-role.md).

**Experiment report configuration**  
The configuration to enable experiment reports. For more information, see [Experiment report configurations for AWS FIS](experiment-report-configuration.md).

**Experiment options**  
Options for the experiment template. For more information, see [Experiment options for AWS FIS](experiment-options.md).

Your account has quotas related to AWS FIS. For example, there is a quota on the number of actions per experiment template. For more information, see [Quotas and limitations](fis-quotas.md).

            "targets": {},
            "actions": {},
            "stopConditions": [],
            "roleArn": "arn:aws:iam::{{123456789012}}:role/{{AllowFISActions}}",
            "experimentReportConfiguration":{},
            "experimentOptions":{},
            "tags": {}
        }
