Election-night traffic analytics need a large burst of capacity, then quiet days afterward. Which cloud benefit should the city leverage?
Select an answer to reveal the explanation.
Short Explanation
Election night is a stadium crowd; Wednesday is empty seats. Elasticity lets you swell the analytics farm for the spike and shrink it after. Pay for the roar, not the empty arena all year.
Full Explanation
Elasticity is the ability to add and remove cloud capacity as workload intensity changes. Civic bursts such as election-night traffic analytics benefit from scaling out temporarily and scaling in afterward. Permanent peak hardware, fixed average sizing that drops peak events, or disabling analytics altogether waste money or lose insight. Chapter 9 lists elasticity among primary cloud benefits for Big Data.
