How does elasticity help a retailer that experiences large traffic spikes during holiday sales?
a.Capacity automatically scales out during spikes and scales in afterward, matching cost to demand
b.Capacity is fixed at the peak level all year, wasting money off-season
c.The retailer must manually order servers weeks ahead of each sale
d.Traffic spikes cause the application to be permanently oversized
解析
Elasticity lets the retailer add capacity during peak periods and remove it when demand falls, so they pay only for what they need. This avoids both over-provisioning year-round and under-provisioning during spikes.
