I agree server-less is not technically accurate.  That&#x27;s why I put it in quotes.  However, in the spectrum of<p>bare metal server &lt;-&gt; VM server &lt;-&gt; Heroku-like PaaS<p>I&#x27;d put this architecture to the right of Heroku.  I have less to worry about from an Ops perspective than I do running the app on Heroku.  On Heroku, I would need to think about and managing one or several processes.  With AWS Lambda, there is no concept of a processes exposed to me like Procfiles expose on Heroku.  That&#x27;s nice in many ways but also limiting in many ways.<p>Also, note that I wasn&#x27;t building this for rock hard and huge scalability production.  I was building it to learn and hopefully help others learn about a fairly new way to build a web application.
