AWS Proton endpoints and quotas - AWS General Reference

AWS Proton endpoints and quotas

The following are the service endpoints and service quotas for this service. To connect programmatically to an AWS service, you use an endpoint. In addition to the standard AWS endpoints, some AWS services offer FIPS endpoints in selected Regions. For more information, see AWS service endpoints. 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.

Note

AWS recommends using Regional STS endpoints within your applications and avoid using the global (legacy) STS endpoint. Regional STS endpoints reduce latency, build in redundancy, and increase session token validity. For more information about configuring your applications to use the regional STS endpoint, see AWS STS Regionalized endpoints in the AWS SDKs and Tools Reference Guide. For more information about the global (legacy) AWS STS endpoint, including how to monitor for use of this endpoint, see How to use Regional AWS STS endpoints in the AWS Security blog.
