What does 'elasticity' refer to in cloud computing?

Elasticity in cloud computing refers to the ability to quickly provision and de-provision resources in response to demand fluctuations. This characteristic allows organizations to automatically adjust their cloud resources up or down based on usage. For instance, during peak times when demand for applications or services increases, a cloud provider can automatically allocate more resources to handle the load. Conversely, when demand decreases, excess resources can be released to save costs and optimize efficiency.

This flexibility is a key benefit of cloud services, enabling businesses to respond swiftly to changing market conditions without the need for significant upfront investment in physical infrastructure. Organizations can ensure they have the right amount of computing resources at any given time, leading to improved performance and cost-effectiveness.

The other options, while relevant in their own contexts, do not directly address the concept of elasticity in cloud computing.
