A stateful legacy permitting app cannot safely run multiple writers. Which short-term scaling choice is safest?
Select an answer to reveal the explanation.
Short Explanation
If the old permitting app freaks out with two writers, don’t force a crowd—give the one box more muscle for now. Vertical scaling is the safer short-term move when horizontal multi-writer just isn’t compatible. Rebuild for scale-out later; don’t corrupt permits tonight.
Full Explanation
Application architecture constrains scaling choices. Stateful legacy systems that cannot safely support multiple writers often require vertical scaling in the short term. Choosing horizontal scale-out without redesign risks data corruption or inconsistent state; Cloud+ scenarios test matching the approach to architectural limits.
