Answer: Amazon Redshift

Amazon Redshift is AWS's fully managed, petabyte-scale data warehouse service designed specifically for large-scale data analytics workloads. It can handle petabytes of data and provides high-performance querying capabilities using columnar storage and massively parallel processing (MPP) architecture. **Why other options are incorrect:** - **Amazon DynamoDB**: A NoSQL database service for key-value and document data, not designed for petabyte-scale data warehousing - **Amazon RDS**: A managed relational database service for OLTP workloads, not optimized for large-scale analytics - **Amazon ElastiCache**: An in-memory caching service for improving application performance, not a data warehouse solution
