A company has two different types of reporting needs on their 200-GB data warehouse:
Data scientists run a small number of concurrent ad hoc SQL queries that can take several minutes each to run. Display screens throughout the company run many fast SQL queries to populate dashboards.
Which design would meet these requirements with the LEAST cost?
A. Replicate relevant data between Amazon Redshift and Amazon DynamoDB. Data scientists use Redshift. Dashboards use DynamoDB.
B. Configure auto-replication between Amazon Redshift and Amazon RDS. Data scientists use Redshift. Dashboards use RDS.
C. Use Amazon Redshift for both requirements, with separate query queues configured in workload management.
D. Use Amazon Redshift for Data Scientists. Run automated dashboard queries against Redshift and store the results in Amazon ElastiCache. Dashboards query ElastiCache.
