Hi, I am the author of this article and I have to say I partly agree with you. For huge scale deployments Ansible is not very good and the alternatives mentioned at the end of the article (Salt and StackStorm) seem to be better suited for such deployment. When the scale is smaller, though, the push model is in my opinion nice as it does not require setting up a server. You can start right away. Also, reusing SSH means (almost) no dependencies as mentioned in the article. It may all depend on the use case though, but in my opinion running Ansible is much better than manual configuration or using shell scripts.
