/**
*
* The load balancer configuration to use with a service or task set.
*
*
* When you add, update, or remove a load balancer configuration, Amazon ECS starts a new deployment with the updated
* Elastic Load Balancing configuration. This causes tasks to register to and deregister from load balancers.
*
*
* We recommend that you verify this on a test environment before you update the Elastic Load Balancing configuration.
*
*
* A service-linked role is required for services that use multiple target groups. For more information, see Using
* service-linked roles in the Amazon Elastic Container Service Developer Guide.
