A cloud infrastructure that can quickly adjust to meet peak demand is referred to as what?

1. Elasticity

2. Federation

3. Automation

4. Caching

The correct answer is: Elasticity

The term that describes a cloud infrastructure capable of quickly adjusting to meet peak demand is known as elasticity. Elasticity refers to the ability of a cloud environment to dynamically allocate and deallocate resources based on the changing needs of an application or service. This means that as demand increases, additional resources such as computing power, storage, or bandwidth can be provisioned promptly, ensuring that performance remains consistent and efficient. Conversely, when demand decreases, resources can be scaled down to reduce costs. In cloud environments, elasticity allows businesses to be more responsive, ensuring that they can handle traffic spikes or increased workloads without over-provisioning resources during periods of low demand. This characteristic is essential for maintaining optimal performance and cost-effectiveness in cloud computing. Other terms like federation, automation, and caching do not pertain directly to the ability to scale infrastructure with demand in the same way. Federation generally refers to the interconnection of different cloud services or providers, automation pertains to the use of tools and scripts to manage cloud resources, and caching is about storing copies of data to improve access speed, none of which capture the essence of dynamically adjusting resources based on demand as elasticity does.
