Which concept refers to designing a system capable of handling increased demand by adding resources?
Scalability
Redundancy
Resilience
Availability
Scalability is the ability of a system to handle a growing amount of work by adding resources. It ensures that as demand increases, the system can scale up or out to maintain performance levels. Resilience refers to a system's ability to recover from failures, availability is about the system being accessible when needed, and redundancy involves duplicating components to prevent failure but does not directly address increasing demand.
