Which cloud feature primarily addresses the issue of scaling resources up or down as needed?

1. Elasticity

2. Scalability

3. Resource Management

4. Cost Efficiency

The correct answer is: Elasticity

The concept of elasticity in cloud computing refers to the ability of a cloud service to automatically scale resources up or down based on current demand. This feature allows organizations to efficiently respond to fluctuations in workloads. For instance, during peak usage times, additional resources can be provisioned, and when demand decreases, those resources can be released, optimizing performance and cost. Elasticity is particularly beneficial for applications with variable workloads, ensuring that services remain available and performant without overspending on resources that are not in use. By dynamically adjusting resource allocation, elasticity enables organizations to maintain efficient operations and adapt to changing business conditions swiftly. While scalability is also important, it generally refers to the capability of a system to handle a growing amount of work or its potential to accommodate growth. It encompasses both vertical scaling (adding more power to an existing machine) and horizontal scaling (adding more machines). However, elasticity focuses specifically on the automated aspect of resource management in response to immediate needs, making it the primary feature for addressing resource scaling on demand.
