# Amazon ECS endpoints and quotas
<a name="ecs-service"></a>

To connect programmatically to an AWS service, you use an endpoint. AWS services offer the following endpoint types in some or all of the AWS Regions that the service supports: IPv4 endpoints, dual-stack endpoints, and FIPS endpoints. Some services provide global endpoints. For more information, see [AWS service endpoints](rande.md).

Service quotas, also referred to as limits, are the maximum number of service resources or operations for your AWS account. For more information, see [AWS service quotas](aws_service_limits.md).

The following are the service endpoints and service quotas for this service.

## Service quotas
<a name="limits_ecs"></a>

The following are Amazon ECS service quotas.

Most of these service quotas, but not all, are listed under the Amazon Elastic Container Service (Amazon ECS) namespace in the Service Quotas console. To request a quota increase, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-increase.html) in the *Service Quotas User Guide*.

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/general/latest/gr/ecs-service.html)

**Note**  
<a name="service-quotas-ecs-note-1"></a>Services configured to use Amazon ECS service discovery have a limit of 1,000 tasks per service. This is due to the AWS Cloud Map service quota for the number of instances per service. For more information, see [AWS Cloud Map service quotas](https://docs.aws.amazon.com/general/latest/gr/cloud_map.html) in the *Amazon Web Services General Reference*.

**Note**  
<a name="service-quotas-ecs-note-2"></a>In practice, task launch rates are also dependent on other considerations such as container images to be downloaded and unpacked, health checks and other integrations enabled, such as registering tasks with a load balancer. You will see variations in task launch rates compared with the quotas represented above based on the features that you have enabled for your Amazon ECS services. For more information, see [speeding up Amazon ECS deployments](https://docs.aws.amazon.com/AmazonECS/latest/bestpracticesguide/deployment.html) in the Amazon ECS Best Practices Guide.

## AWS Fargate quotas
<a name="service-quotas-fargate"></a>

The following are Amazon ECS on AWS Fargate service quotas and are listed under the **AWS Fargate** service in the Service Quotas console.

New AWS accounts might have initial lower quotas that can increase over time. Fargate constantly monitors the account usage within each Region, and then automatically increases the quotas based on your usage. You can also request a quota increase for values that are shown as adjustable, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-increase.html) in the *Service Quotas User Guide*.

[\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/general/latest/gr/ecs-service.html)

**Note**  
The default values are the initial quotas set by AWS, which are separate from the actual applied quota value and maximum possible service quota. For more information, see [Terminology in Service Quotas](https://docs.aws.amazon.com/servicequotas/latest/userguide/intro.html#intro_getting-started) in the *Service Quotas User Guide*.

**Note**  
Fargate additionally enforces Amazon ECS tasks and Amazon EKS pods launch rate limits. For more information, see [AWS Fargate throttling quotas](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/throttling.html) in the *Amazon ECS Developer Guide*.
