Key points
- •A Stack is the deployable, manageable unit grouping all resources from one template
- •Parameters make one template reusable across environments/accounts with different input values
- •Outputs expose specific stack values for external use, including cross-stack references
- •Splitting infrastructure into multiple logically-related stacks (using outputs/cross-stack references) improves manageability over one giant monolithic template
