Explore nested stacks vs StackSets

At NovaTech, your team needs to organize CloudFormation at scale. Use the nested stacks and StackSets explorer to compare these two approaches for organizing CloudFormation at scale.

Question: Your organization needs to deploy an identical IAM security baseline to 50 AWS accounts across three regions. Which CloudFormation feature should you use?
