Peak permit season needs more capacity on identical web instances rather than enlarging a single box. Which scaling approach should the city use?
Select an answer to reveal the explanation.
Short Explanation
Horizontal scaling is opening more checkout lanes instead of making one cashier eight feet tall. Add identical web instances when permits flood in, then shed them when quiet returns. Same shape, more copies—that’s the web-tier playbook.
Full Explanation
Horizontal scaling adds or removes instances of the same role to match demand. It suits stateless or load-balanced web tiers where capacity grows with instance count. Cloud+ scaling objectives distinguish this from vertical scaling, which changes the size of an existing instance.
