# Services {% hint style="info" %} This page was generated from content adapted from the [AWS Developer Guide](https://github.com/awsdocs/amazon-ecs-developer-guide.git) {% endhint %} ## Service load balancing * **Note**\ When you use tasks sets, all the tasks in the set must all be configured to use Elastic Load Balancing or to not use Elastic Load Balancing. ## Service throttle logic * **Important**\ Tasks that are stopped after they reach the `RUNNING` state don't start the throttle logic or the associated service event message. For example, assume that failed Elastic Load Balancing health checks for a service cause a task to be flagged as unhealthy, and Amazon ECS deregisters it and stops the task. At this point, the tasks aren't throttled. Even if a task's container command immediately exits with a non-zero exit code, the task already moved to the `RUNNING` state. Tasks that fail immediately because command errors don't cause the throttle or the service event message. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
