The ease in which I was able to spin up containers, connect them together and deploy my application with minimal effort. There really isn't anything I dislike about this product. If you want something simple then this may not be what you are looking for. However if your organization needs an easy way to manage many docker applications at once and easily scale out/in when needed, this will work great! We have been using Nebulas to orchestrate our cloud native microservices. This has allowed us to quickly create new projects without having to worry about managing infrastructure ourselves.
