AWS Certified Solutions Architect Associate SAA-C03 Practice Question
Which statement best describes Amazon S3 when compared with relational database storage?
It is a fully managed relational database service that supports engines such as MySQL and PostgreSQL out of the box.
It stores data in a structured table format with a rigid schema defined in advance, making it ideal for relational queries.
It provides block-level storage volumes that must be attached to EC2 instances and formatted with a file system.
It stores data as objects in buckets without requiring a predefined schema, so it is not suitable as the primary storage for relational database workloads.
Amazon S3 is an object storage service. Objects are stored in buckets with a key and optional metadata, and there is no requirement to define tables, columns, or other rigid relational structures before storing data. Because of this schemaless design, S3 is not used as the primary storage engine for traditional relational database workloads that rely on fixed schemas and SQL relationships. Relational data is better hosted on services such as Amazon RDS or Amazon Aurora, while S3 remains ideal for unstructured or semistructured data, backups, and data-lake use cases.
