Code runs only when an event occurs, and capacity changes with the number of requests.
Choose the matching compute characteristics.
Choose TWO appropriate statements.
Lambda runs event-driven code without direct server management, while Auto Scaling adjusts resource capacity as demand changes.
Detailed explanation
Auto Scaling changes capacity rather than keeping it fixed.
Auto Scaling changes capacity rather than keeping it fixed.
Auto Scaling adjusts capacity based on load or a schedule to provide elasticity.

Foundation review
Different controls
Lambda abstracts server provisioning; Auto Scaling changes the amount of provisioned capacity for supported resources.
Demand response
Both concepts address variable demand, but they operate at different layers of the compute design.
