The most important thing is, that you can easily set up your own cluster for any use case by yourself! You don't have to rely only on their support team. They provide great docs which help me during my development process. I think they could add more options like adding new nodes or moving existing ones around etc. It's not possible at this time but it would be really cool if we had some kind of control over our resources. For us as an application developer who doesn´t want to depend too much on third party services there are many advantages when using infinibuilder instead of setting up everything manually from scratch.
