Elastic Network Interface Trunking – Amazon Elastic Container Service

Each Amazon ECS task that uses the awsvpc network mode receives its own elastic network interface (ENI), which is attached to the container instance that hosts it. Because each task using the awsvpc network mode requires an ENI, only two such tasks can be run on this instance type.

Amazon ECS supports launching container instances with increased ENI density using supported Amazon EC2 instance types. This configuration allows for launching 10 tasks on the container instance instead of the current two.
