/**
* Interface for accessing Amazon ECS.
*
*
* Amazon EC2 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 of EC2 instances. Amazon ECS lets you launch
* and stop container-enabled 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 like security groups, Amazon EBS
* volumes, and IAM roles.
*
*
* 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 EC2 Container Service 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 instantiation 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.
*
*
* You can optionally specify a deployment configuration for your service.
* During a deployment (which is triggered by changing the task definition
* of a service with an UpdateService operation), the service
* scheduler uses the minimumHealthyPercent and
* maximumPercent parameters to determine the deployment
* strategy.
*
*
* If the minimumHealthyPercent is below 100%, the scheduler
* can ignore the desiredCount temporarily during a deployment.
* For example, if your service has a desiredCount of four
* tasks, a minimumHealthyPercent of 50% allows the scheduler
* to stop two existing tasks 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 it is 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 running tasks during a deployment, which enables you to
* define the deployment batch size. For example, if your service has a
* desiredCount of four tasks, a maximumPercent
* value of 200% starts 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 attempts to balance
* them across the Availability Zones in your cluster with 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).
*
*
* -
*
* 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.

/**
*
* Modifies the desired count, deployment configuration, or task definition
* used in a service.
*
*
* You can add to or subtract from the number of instantiations of a task
* definition in a service by specifying the cluster that the service is
* running in and a new desiredCount parameter.
*
*
* You can use UpdateService to modify your task definition and
* deploy a new version of your service.
*
*
* You can also update the deployment configuration of a service. When a
* deployment is triggered by updating the task definition of a service, the
* service scheduler uses the deployment configuration parameters,
* minimumHealthyPercent and maximumPercent, to
* determine the deployment strategy.
*
*
* If the minimumHealthyPercent is below 100%, the scheduler
* can ignore the desiredCount temporarily during a deployment.
* For example, if your service has a desiredCount of four
* tasks, a minimumHealthyPercent of 50% allows the scheduler
* to stop two existing tasks 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 it is hosted on is
* reported as healthy by the load balancer.
*
*
* The maximumPercent parameter represents an upper limit on
* the number of running tasks during a deployment, which enables you to
* define the deployment batch size. For example, if your service has a
* desiredCount of four tasks, a maximumPercent
* value of 200% starts four new tasks before stopping the four older tasks
* (provided that the cluster resources required to do this are available).
*
*
* When UpdateService stops a task during a deployment, the
* equivalent of docker stop is issued to the containers
* running in the task. This results in a SIGTERM and a
* 30-second timeout, after which SIGKILL is sent and the
* containers are forcibly stopped. If the container handles the
* SIGTERM gracefully and exits within 30 seconds from
* receiving it, no SIGKILL is sent.
*
*
* When the service scheduler launches new tasks, it attempts to balance
* them across the Availability Zones in your cluster with 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).
*
*
* -
*
* 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.
