Overview
While scalability is about the capacity to handle more load, elasticity is about the automation of that process. It is a core feature of cloud computing, allowing organizations to pay only for the resources they need at any given moment.
How it Works
Monitoring tools track metrics like CPU usage or request volume. When a threshold is reached, the system automatically provisions or de-provisions resources (e.g., using AWS Auto Scaling).
Benefits
- Cost Efficiency: No need to pay for idle resources.
- Performance: Ensures the system can handle sudden traffic spikes.
