Which of the following cloud services allows for dynamic scaling based on demand?

Chef
Elasticity
Containers
Load Balancing

The correct answer is: Elasticity

Elasticity refers to the ability of a cloud service to automatically scale resources up or down based on current demand. In a cloud environment, this means that when there is an increase in usage, the system can provision additional resources to meet that demand. Conversely, when demand decreases, resources can be deallocated, ensuring that costs are managed effectively while maintaining performance. This characteristic is essential for applications that experience variable workloads, allowing organizations to maintain optimal performance without over-provisioning resources. While Chef, containers, and load balancing have their own roles in cloud computing, they do not specifically define the dynamic scaling capabilities inherent to elastic services. Chef is a configuration management tool, containers provide a way to package applications, and load balancing is a technique for distributing workloads across multiple resources but does not inherently adjust the resources themselves. Therefore, elasticity is the key concept that directly relates to dynamic scaling, making it the correct choice.
