Jelastic can run docker in two separate ways: 1) the way when the image is running as a plain VZ container (advantage: many extra features become available, disadvantage: compatibility with native docker is not 100%) 2) run via Native docker engine, but instead of VM (like everyone does) elastic VZ container is used as a host machine for running embedded containers. Compatibility with classical docker is 100% + vertical scaling as an extra feature, because of VZ layer on top. Basically both ways of running docker images allows to have flexible and managed resource management so vertical scaling is indeed available for both of them. BTW, Kubernetes in Jelastic is using the same approach that makes Jelastic only available platform for K8S on the market with "pay as you use" billing model, where you can pay only for consumed resources and not for the limits as everyone does.
