With a detailed billing module, this can be used as a complete public cloud implementation, and we are waiting to see that module from OpenNebula. Most of the competitors are offering some sort of billing software to transform their installation to work as a small-sized public cloud, but those offerings from OpenNebula are still missing. With the addition of this module, it will bring completeness to the overall offerings. We hope that OpenNebula listens to this and bring quickly the module.
The structure of the documentation is very messy. You can't find anything you want. When you search for features you are faced with many different topics and they don't have any connection to each other. Compared to the documentation for VMware, it is really simple and messy. You find many topics that are not related to each other and you have to read all of the documents from beginning to end if you want to know how to set something up. For example, if you want to set up Kubernetes then you should be able to search for the top and learn how to do it. However, with OpenNebula, it is too difficult to do that. They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work. They keep postponing it to the next version and we are impatiently waiting for it. When the ability to hot-add or remove RAM and CPU inside the virtual machine is working, it will be very good. The community has some weaknesses. For example, the answers are sometimes very short and contain no detail, like "Working on it", without answering with specifics. Another weakness is that you have to develop a third-party portal from outside and connect using the NSX API directly from it.
They should add more features like object storage. They should improve some management feature for the storage, for example, they should put third party staff. The integration features should also be improved but I believe they are working on it. They should add HDM and HDS features.
