Updating AWS SDK defaults – AWS STS service endpoint and Retry Strategy
AWS announces important configuration updates coming July 31st, 2025, affecting AWS SDKs and CLIs default settings. Two key changes include switching the AWS Security Token Service (STS) endpoint to regional and updating the default retry strategy to standard. These updates aim to improve service availability and reliability by implementing regional endpoints to reduce cross-regional dependencies and introducing token-bucket throttling for standardized retry behavior. Organizations should test their applications before the release date and can opt-in early or temporarily opt-out of these changes. These updates align with AWS best practices for optimal service performance and security.
