There have been challenges related to software bugs, especially regarding long-term licensing options and issues within our customer network. They should test the software to resolve the issues before the next release.

The product lacks some virtualization capabilities, making it an area for improvement where the solution can focus on providing users with more virtualization capabilities related to disk systems.

Areas for improvement in Nutanix Kubernetes Engine (NKE) include upgrading management capabilities and enhancing the user interface for improved usability. While basic tasks like cluster creation and scaling are straightforward, advanced functionalities such as replication and recovery may need to be performed optimally. 

Future versions of NKE should address these limitations to enhance functionality, particularly in troubleshooting, replication, and disaster recovery scenarios where NKE may fall short compared to other platforms like OpenShift.

I have issues with the product's interoperability. 

We have Oracle in production. We need a backup of production clusters. We need to ensure if something goes down, we have a backup ready to go that can handle the workload. We'd prefer Kubernetes would offer this instead of us having to go to a third-party solution.

When we create clusters with two loads, the capacity is limited. If we want to override memory, we cannot.

I would like to have more nodes for availability and storage.

There have been cases where we've deployed with Karbon and haven't seen that it includes errors. There's no way to see them without going into the logs. It would be helpful to have a more verbose GUI, more information, in order to know what's going on with the installation and the process. Karbon is a relatively new feature for Nutanix and the documentation is not completely up to date.  

The user interface could be improved.

I would like to be able to do a dynamic resource increase and make adjustments. That would be a fantastic feature. It would automatically increase them and it would automatically discard them.

In the next release, I would like to have automatic dynamic scaling, both upscaling and downscaling.
