"Modelling" describes the intellectual work before the implementation.

It indentifies the major use cases, looks for the primary
concepts and designs the outline of the necessary classes and
their interactions.

It is an essential preparation for the actual implementation --
for any non-trivial task...

It is the task of the modelling phase to answer such questions.

No, it is not necessary.

You should read:

No, because it is not necessary.

It is the easiest and most standard solution.

But there is also an SSL enabled ZServer (as a third party product).
I do not know its name -- search for it if you mistrust Apache...
