A stable solution that can be deployed in parts to improve its robustness and reliability
Our clients are usually enterprise businesses. IBM Cloud Kubernetes Service is a good solution because our customer requires very rapid deployment, and the solution is critical for his business. If the system is down, the lawyer cannot send documents, and people may be in jail. Overall, I rate IBM Cloud Kubernetes Service an eight out of ten.

Intelligent autoscaling has cut compute costs and now manages ephemeral workloads efficiently
I think overall Spot is quite good. The UI is powerful, but it can feel a bit dense for some new users. More guided onboarding would help teams adopt advanced features faster, and deeper insights into Kubernetes resource usage would be beneficial. Overall, it is a really good platform that is quite mature and stable. I chose a rating of nine because it may sometimes be a bit overwhelming for newcomers, and there are also a few areas in which the EKS Kubernetes level granularity is a little missing. Overall, I think Spot is a really good and stable tool.
