# DescribeServiceRevisions
Describes one or more service revisions.
A service revision is a version of the service that includes the values for the Amazon ECS resources (for example, task definition) and the environment resources (for example, load balancers, subnets, and security groups). For more information, see [Amazon ECS service revisions](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-revision.html).
You can't describe a service revision that was created before October 25, 2024.
