A Constraint Can Be Useful

Constraints are often described as obstacles. Some are. Others are the reason a design becomes clear.

“The public site must remain static” removes many possible architectures. It also makes several decisions easier. Content is prepared during the build. Server secrets cannot drift into the public site. Pages must remain useful without a running application process.

A useful constraint is specific enough to guide action and connected to a real need. A vague rule such as “keep it simple” does not tell us which trade-off to choose.

Constraints should still be questioned. A rule that once protected the system may become unnecessary. The important step is to understand what the rule protects before removing it. Freedom without that context can bring back an old problem in a new form.
