Question
A data analytics company has an Amazon Redshift cluster that consists of several reserved nodes. The cluster is experiencing unexpected bursts of usage because a team of employees is compiling a deep audit analysis report. The queries to generate the report are complex read queries and are CPU intensive. Business requirements dictate that the cluster must be able to service read and write queries at all times. A solutions architect must devise a solution that accommodates the bursts of usage. Which solution meets these requirements MOST cost-effectively?

Explanation
Support virtually unlimited concurrent users and concurrent queries, with consistently fast query When you turn on concurrency scaling, Amazon Redshift automatically adds additional cluster capacity to process an increase in both read and write queries. Users see the most current data, whether the queries run on the main cluster or a concurrency- scaling cluster. You're charged for concurrency-scaling clusters only for the time they're actively running queries. https://docs.aws.amazon.com/redshift/latest/dg/concurrency-scaling.html
