What is the ability of cloud resources to scale up and down based on demand called?

• A. Scalability
• B. Elasticity
• C. Flexibility
• D. Adjustability

Answer: (B)

The ability of cloud resources to scale up and down based on demand is referred to as elasticity. This concept emphasizes the dynamic adjustment of resources in a cloud environment, allowing for the provisioning of additional resources when demand increases, and the reduction of resources when demand decreases, thereby optimizing cost and performance. Elasticity is a key characteristic of cloud computing that enables organizations to efficiently meet workload demands without over-provisioning resources. Scalability, while related, typically describes the capacity of a system to handle growing amounts of work or its potential to accommodate growth without affecting performance. Elasticity goes a step further by specifically focusing on the automatic and on-demand nature of these adjustments in response to real-time usage patterns.
