A web store automatically adds computing capacity on the morning of a sale and releases that capacity the same night. Which cloud property is this?
Select an answer to reveal the explanation.
Short Explanation
Elasticity is a pop-up counter you open for the rush and fold away when the rush is over. You add capacity on the morning of the sale and release it that night, which is more than simply growing and staying grown. Scalability is the ability to get bigger, and the release that same night is what makes this elasticity.
Full Explanation
Elasticity is the ability to add resources when demand rises and to release them when demand falls, usually automatically. The web store adds capacity on the morning of the sale and releases it that night, so the deployment tracks the spike in both directions. Scalability is the near miss. It is the ability to handle more load, and a design that only grows still qualifies, while this stem gives the capacity back the same night. Calling the release scalability collapses the two words. A static reservation that grows and never releases is that one-way growth, not the nightly return to baseline. Multitenancy means several customers share infrastructure while staying isolated. Sharing hardware does not describe the morning add and the nightly release. Exam caveat: if a stem only says the system can grow, do not assume it shrinks. The release is the detail that selects elasticity. Operational check: record the capacity count before the sale, during the morning spike, and after the nightly release, and confirm the count returns to the baseline.
