I think the Docker based self-hosted PAASs (Deis, Flynn etc) is squeezing the smaller PAAS offering at the low end, and Elastic Beanstalk&#x2F;Azure&#x2F;Google CloudDB is killing it at the high end.<p>Why would you use &lt;insert random small PAAS company&gt; when you can deploy your own on AWS and then use their managed DB service?
