<a name="endpoints-quotas"></a>

## Service endpoints
<a name="endpoints"></a>

To connect programmatically to an AWS service, you use an *endpoint*. An endpoint is the URL of the entry point for an AWS web service. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. The following table lists the service endpoints for EMR Serverless. For more information, refer to [AWS service endpoints](https://docs.aws.amazon.com/general/latest/gr/rande.html).

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

*Service quotas*, also known as *limits*, are the maximum number of service resources or operations that your AWS account can use. EMR Serverless collects service quota usage metrics every minute and publishes them in the `AWS/Usage` namespace.

**Note**  
New AWS accounts have initial lower quotas that can increase over time. Amazon EMR Serverless monitors account usage within each AWS Region, and then automatically increases the quotas based on your usage.

The following table lists the service quotas for EMR Serverless. For more information, refer to [AWS service quotas](https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html).



| Name | Default limit | Adjustable? | Description | 
| --- | --- | --- | --- | 
| Max concurrent vCPUs per account | 16 | Yes | The maximum number of vCPUs that can concurrently run for the account in the current AWS Region.<br />Valid Period: 1 minute<br />Valid Statistics: Sum |
