- A container’s health is monitored via [CLB](#clb) or [ALB](#alb). Those can also be used to address a containerized service. When using an ALB you do not need to handle port contention (i.e. services exposing the same port on the same host) since an ALB’s target groups can be associated with ECS-based services directly.
- ECS supports multiple log drivers (awslogs, splunk, fluentd, syslog, json, ... ). Use [`awslogs`](http://docs.aws.amazon.com/AmazonECS/latest/developerguide/using_awslogs.html) for CloudWatch (make sure a group is made for the logs first). [Drivers such as fluentd are not enabled by default](https://github.com/aws/amazon-ecs-agent/issues/535). You can, install the agent and enable the driver by adding `ECS_AVAILABLE_LOGGING_DRIVERS='["awslogs","fluentd"]'` to `/etc/ecs/ecs.config`.

- [This blog from Convox](https://convox.com/blog/ecs-challenges/) (and [commentary](https://news.ycombinator.com/item?id=11598058)) lists a number of common challenges with ECS as of early 2016.
- It is possible to optimize disk clean up on ECS. By default, the unused containers are deleted after 3 hours and the unused images after 30 minutes. These settings can be changed by adding `ECS_ENGINE_TASK_CLEANUP_WAIT_DURATION=10m` and `ECS_IMAGE_CLEANUP_INTERVAL=10m` to `/etc/ecs/ecs.config`.
