/**
* Interface for accessing Amazon ECS.
*
* Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
* {@link com.amazonaws.services.ecs.AbstractAmazonECS} instead.
*
*
*
* Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it
* easy to run, stop, and manage Docker containers on a cluster. You can host your cluster on a serverless
* infrastructure that is managed by Amazon ECS by launching your services or tasks using the Fargate launch type. For
* more control, you can host your tasks on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) instances that you
* manage by using the EC2 launch type. For more information about launch types, see Amazon ECS Launch Types.
*
*
* Amazon ECS lets you launch and stop container-based applications with simple API calls, allows you to get the state
* of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features.
*
*
* You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs,
* isolation policies, and availability requirements. Amazon ECS eliminates the need for you to operate your own cluster
* management and configuration management systems or worry about scaling your management infrastructure.

*
* Runs and maintains a desired number of tasks from a specified task definition. If the number of tasks running in
* a service drops below desiredCount, Amazon ECS spawns another copy of the task in the specified
* cluster. To update an existing service, see UpdateService.
*
*
* In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind
* a load balancer. The load balancer distributes traffic across the tasks that are associated with the service. For
* more information, see Service Load
* Balancing in the Amazon Elastic Container Service Developer Guide.
*
*
* You can optionally specify a deployment configuration for your service. During a deployment, the service
* scheduler uses the minimumHealthyPercent and maximumPercent parameters to determine the
* deployment strategy. The deployment is triggered by changing the task definition or the desired count of a
* service with an UpdateService operation.
*
*
* The minimumHealthyPercent represents a lower limit on the number of your service's tasks that must
* remain in the RUNNING state during a deployment, as a percentage of the desiredCount
* (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster
* capacity. For example, if your service has a desiredCount of four tasks and a
* minimumHealthyPercent of 50%, the scheduler can stop two existing tasks to free up cluster capacity
* before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy
* if they are in the RUNNING state. Tasks for services that do use a load balancer are
* considered healthy if they are in the RUNNING state and the container instance they are hosted on is
* reported as healthy by the load balancer. The default value for minimumHealthyPercent is 50% in the
* console and 100% for the AWS CLI, the AWS SDKs, and the APIs.
*
*
* The maximumPercent parameter represents an upper limit on the number of your service's tasks that
* are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the
* desiredCount (rounded down to the nearest integer). This parameter enables you to define the
* deployment batch size. For example, if your service has a desiredCount of four tasks and a
* maximumPercent value of 200%, the scheduler can start four new tasks before stopping the four older
* tasks (provided that the cluster resources required to do this are available). The default value for
* maximumPercent is 200%.
*
*
* When the service scheduler launches new tasks, it determines task placement in your cluster using the following
* logic:
*
*
* -
*
* Determine which of the container instances in your cluster can support your service's task definition (for
* example, they have the required CPU, memory, ports, and container instance attributes).
*
*
* -
*
* By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although
* you can choose a different placement strategy) with the placementStrategy parameter):
*
*
* -
*
* Sort the valid container instances by the fewest number of running tasks for this service in the same
* Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each
* have zero, valid container instances in either zone B or C are considered optimal for placement.
*
*
* -
*
* Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous
* steps), favoring container instances with the fewest number of running tasks for this service.

*
*
* -
*
* If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount

* and the container instance they are hosted on is reported as healthy by the load balancer.
