Best practice for managing Textract Custom Adapters and BDA Blueprints across multiple environments (Dev/QA/Staging/Prod) centralized account vs per-environment?

Question

We are implementing Amazon Textract Custom Adapters and Amazon Bedrock Data Automation (BDA) with optimized blueprints for document processing across different environments: Dev, Staging, and Production.
We are evaluating two architecture approaches and would appreciate guidance from AWS on which is recommended:
Option A: Per-Environment
Each environment (Dev, QA, Staging, Production) has its own AWS account with its own copy of the Textract adapters and BDA blueprints.
- For Textract: Moving a trained adapter between accounts requires filing an AWS Support ticket for each move. Every model update means filing new tickets and waiting.
- For BDA: The optimized blueprint would need to be exported and imported into each account. 
Option B: Centralized AI Hub
One dedicated AWS account hosts all Textract adapters and BDA blueprints. Each environment (Dev, Staging, Production) connects to the Hub using cross-account roles to consume the AI services. Each environment would have its own model version within the Hub.

Our questions:
1. What is the AWS recommended architecture for managing Textract Custom Adapters and BDA optimized blueprints across multiple environments in a regulated industry?
2. For Textract: Is there a way to move trained adapters between accounts without filing support tickets? Or is a centralized account the recommended approach to avoid this bottleneck?
3. For BDA: When exporting an optimized blueprint (after running blueprint instruction optimization with ground truth) and importing it into another account, does the optimization carry over? Or does the blueprint lose the optimization improvements?
4. For a centralized Hub: What is the recommended way to manage separate model versions per environment (Dev/QA/Staging/Prod) within the same account? Is tag-based access control (ABAC) sufficient for environment segregation, or are there other patterns AWS recommends?
5. How should cost attribution work in a centralized model? Can we use resource tags to separate costs by environment and project in AWS Cost Explorer?
Any guidance, documentation references, or examples of this pattern in practice would be very helpful.

Thank you.

Based on AWS best practices for managing shared resources across multiple environments, I can provide guidance on your architecture decision:

**Recommended Architecture Approach:**

The centralized AI Hub approach (Option B) aligns with AWS recommended practices for cross-environment resource sharing. This pattern involves deploying and managing shared resources - in your case, Textract Custom Adapters and BDA blueprints - in a centrally managed account, then providing access to these resources across various environments. This approach enables teams to efficiently use and manage shared resources without the need to replicate their setup in each environment.

By centralizing the management of these AI/ML resources, your development teams can focus more on the functionality of their workloads rather than spending time and effort managing complex infrastructure components and dealing with the operational overhead of moving models between accounts.

**Benefits of the Centralized Approach:**

- **Reduces redundancy** by eliminating the need to maintain multiple copies of the same adapters and blueprints
- **Promotes standardization** across your organization by ensuring all environments use consistent, approved versions
- **Simplifies operations** by avoiding the support ticket bottleneck for moving Textract adapters between accounts
- **Enables better governance** through centralized control of your AI/ML assets

**Implementation Considerations:**

For managing separate versions per environment within the centralized account, you should implement proper access controls and resource organization. The platform team managing the AI Hub should provide APIs or mechanisms that individual environment teams can use to consume the shared resources as needed.

For cost attribution in a centralized model, resource tagging is the appropriate mechanism to separate costs by environment and project, allowing you to track usage and costs through AWS Cost Explorer even when resources are centrally managed.

**Multi-Environment Strategy:**

While centralizing your AI/ML resources, you should still maintain multiple environments for your application workloads. This supports experimentation, development, and testing while reducing risk. Sandbox environments can have minimized controls for experimentation, while environments approaching production should implement more rigorous controls. This separation allows you to test changes to your document processing pipelines safely before promoting them to production.

For service-specific questions about Textract adapter migration capabilities and BDA blueprint optimization persistence during export/import, I recommend engaging AWS Support or your AWS account team, as these involve detailed technical implementation specifics of those particular services.
