- Domain specific presigned URL's can be generated through dynamodb to route users to correct domain - central proxy app can authenticate existing users with company IDP -> retrieve presigned url for users dept from dynamodb -> redirect user to sagemake domain without needing direct auth on AWS

A. Use the SageMaker CreatePresignedDomainUrl API to generate a presigned URL for each domain according to the DynamoDB table. Pass the presigned URL to the proxy application. The AWS documentation mentions the CreatePresignedDomainUrl API, which generates a presigned URL that authenticates a user to a specified Amazon SageMaker Domain. By using this API, the company can generate presigned URLs for each department's SageMaker Studio domain based on the information stored in the DynamoDB table. These presigned URLs can then be passed to the central proxy application, which can authenticate users using the company's existing Identity Provider (IdP) and provide them with the appropriate presigned URL for their department's SageMaker Studio domain. When the user accesses the presigned URL, they will be automatically authenticated and routed to the corresponding SageMaker Studio domain.
