Production and storage

Buildings produce continuously and stop at your storage cap. Time spent at the cap is time producing nothing, so a full vault is a problem rather than an achievement.

Your real capacity is the building capacity scaled by storage research and any premium bonus. The number the game clamps against is the scaled one, not the raw building value.

Upkeep

Troops eat. A large army with thin food production drains you between fights, which is why army size is a decision and not simply a score.
