If the number of tasks running in a service drops below <code>desiredCount</code>, Amazon ECS spawns another copy of the task in the specified cluster. To update an existing service, see <a>UpdateService</a>.</p> <p>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 <a href=\"http://docs.aws.amazon.com/AmazonECS/latest/developerguide/service-load-balancing.html\">Service Load Balancing</a> in the <i>Amazon Elastic Container Service Developer Guide</i>.</p> <p>You can optionally specify a deployment configuration for your service. During a deployment, the service scheduler uses the <code>minimumHealthyPercent</code> and <code>maximumPercent</code> parameters to determine the deployment strategy. The deployment is triggered by changing the task definition or the desired count of a service with an <a>UpdateService</a> operation.</p> <p>The <code>minimumHealthyPercent</code> represents a lower limit on the number of your service's tasks that must remain in the <code>RUNNING</code> state during a deployment, as a percentage of the <code>desiredCount</code> (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a <code>desiredCount</code> of four tasks and a <code>minimumHealthyPercent</code> of 50%, the scheduler can stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that <i>do not</i> use a load balancer are considered healthy if they are in the <code>RUNNING</code> state. Tasks for services that <i>do</i> use a load balancer are considered healthy if they are in the <code>RUNNING</code> state and the container instance they are hosted on is reported as healthy by the load balancer. The default value for <code>minimumHealthyPercent</code> is 50% in the console and 100% for the AWS CLI, the AWS SDKs, and the APIs.</p> <p>The <code>maximumPercent</code> parameter represents an upper limit on the number of your service's tasks that are allowed in the <code>RUNNING</code> or <code>PENDING</code> state during a deployment, as a percentage of the <code>desiredCount</code> (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service has a <code>desiredCount</code> of four tasks and a <code>maximumPercent</code> 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 <code>maximumPercent</code> is 200%.</p> <p>When the service scheduler launches new tasks, it determines task placement in your cluster using the following logic:</p> <ul> <li> <p>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).</p> </li> <li> <p>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 <code>placementStrategy</code> parameter):</p> <ul> <li> <p>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.</p> </li> <li> <p>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.</p> </li> </ul> </li> </ul>"

  "documentation":"<p>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 <a href=\"http://docs.aws.amazon.com/AmazonECS/latest/developerguide/launch_types.html\">Amazon ECS Launch Types</a>.</p> <p>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.</p> <p>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.</p>"
