A solutions architect is designing a document management platform. The platform must handle two storage needs: a cost-effective object storage system for storing millions of PDF files (averaging to in size), and a NoSQL database for metadata lookups (such as document ID, owner, and creation date) with key performance indicators of sub- retrieval latency. The entire architecture must scale automatically to accommodate highly variable traffic volumes. Which two AWS storage and database configurations should the solutions architect implement to satisfy these requirements? (Select TWO.)
- Amazon Simple Storage Service (Amazon S3) Standard storage class to store the PDF documents.Cevap
- Amazon DynamoDB with auto-scaling enabled to store and query the document metadata.Cevap
- CAmazon Aurora MySQL with read replicas configured for manual scaling to handle sudden metadata search spikes.
- DAmazon Elastic File System (Amazon EFS) with daily cross-region backup replication to achieve near-zero Recovery Time Objective (RTO) for document retrieval.
- EAmazon S3 bucket for documents with cross-account replication encrypted using the default AWS-managed KMS key (aws/s3).
Cevap
The solutions architect should combine Amazon Simple Storage Service (Amazon S3) Standard storage class to store the PDF documents, and Amazon DynamoDB with auto-scaling enabled to store and query the document metadata.
Storing unstructured PDF files in Amazon S3 is highly cost-effective and provides the required durability. Pairing it with Amazon DynamoDB for metadata enables fast, low-latency, key-value lookups while utilizing auto-scaling to match fluctuating demand without manual intervention.
