• https://docs.particular.net/architecture/aws/data-stores
• https://docs.particular.net/architecture/azure/data-stores
• https://docs.particular.net/persistence/selecting#making-the-decision-azure
• https://docs.particular.net/persistence/selecting#making-the-decision-aws

This can be restructure to avoid duplication and eventually misalignment.
