What does Elastic mean in cloud computing?

• A. On-demand management of resources
• B. Fully Managed
• C. Expansion and reduction of resources according to requirements
• D. Service available all the time

Answer: (C)

Elastic means the system can automatically grow or shrink resources to match the workload. In cloud computing, this is about scaling up when demand increases and scaling down when demand drops, so performance stays strong without paying for unused capacity. This is usually done with auto-scaling, scaling policies, and load balancing that adjust compute, storage, or other resources based on metrics like CPU usage or request rate. The other ideas describe pay-as-you-go or always-on availability, but they don’t capture the dynamic resizing aspect that elasticity is all about.
