Write libraries instead of services, where possible
&gt; A service has constant administration costs which are paid by the service provider. A properly designed library instead moves these costs to the users of the library.<p>I agree with the articles point, but this introduction, right there, is why it&#x27;s not happening. SaaS turns your startup into a unicorn and yourself into a rich person. Or at least that&#x27;s what you are hoping&#x2F;aiming for. A library is not going to make you a billionaire. Sad but reality.
