 # Prometheus Exporter for Fastly
 
 This module deploys a Prometheus exporter for Fastly using the official
-[fastly/fastly-exporter] Docker image. The implementation uses the [`ecs-task`]
-and [`ecs-service`] modules to deploy the exporter to ECS.
+[fastly/fastly-exporter] Docker image.
+
+## ECS Express Migration
+
+**Note**: This service has been migrated to **AWS ECS Express** (November 2025), 
+which simplifies deployment by automatically managing load balancing, networking, 
+and scaling infrastructure. See [MIGRATION_TO_ECS_EXPRESS.md](MIGRATION_TO_ECS_EXPRESS.md) 
+for details about the migration.
+
+The implementation now uses `aws_ecs_express_gateway_service` instead of the 
+traditional `ecs-task` and `ecs-service` modules, reducing complexity while 
+maintaining the same functionality.
