Which AWS service is a fast, fully managed, petabyte-scale data warehouse that integrates with BI tools?

• A. Amazon Redshift
• B. AWS CodeArtifact
• C. AWS Cloud9
• D. AWS X-Ray

Answer: (A)

A data warehouse service that is designed for fast analytic queries on large datasets and is fully managed by AWS best fits this description. Amazon Redshift is built for this role: it uses columnar storage and a massively parallel processing (MPP) architecture to accelerate complex analytics across petabyte-scale data. Being fully managed means AWS handles provisioning, backups, patching, and maintenance, while you focus on querying and analytics. Redshift also integrates smoothly with BI tools through standard SQL connections via JDBC/ODBC, so tools like Tableau or Power BI can connect directly for dashboards and reports.

The other services don’t match the description: a software artifact repository, an integrated development environment, or an application tracing service, none of which are designed to function as a scalable, petabyte-scale data warehouse integrated with BI tools.
