Correct answer: Move the catalog to an Amazon Elastic File System (Amazon EFS) file system..
Why this is the answer
Moving the catalog to Amazon EFS provides high availability and durability. EFS is a fully managed, scalable file storage service that automatically replicates data across multiple Availability Zones within a region, ensuring high availability and durability. It can be mounted by multiple EC2 instances concurrently, making it suitable for shared access to the catalog. Amazon ElastiCache for Redis is an in-memory data store, not designed for durable, persistent storage of a catalog. Deploying a larger EC2 instance with a larger instance store does not address the high availability or durability requirements, as instance stores are ephemeral and tied to a single instance. Amazon S3 Glacier Deep Archive is for long-term, infrequent access archival storage, not for an actively used website catalog that requires low-latency access.
