The most valuable feature is manageability. From one control, I can manage and monitor my entire cluster.
Also, I like the Prism console of Nutanix.
There are two features, one is data protection that is in-built with Nutanix, and the other is that I can schedule my VM backups. I don't need to buy any third-party software for that. If I have the ESXi to Hyper-V, I need to have third-party software. But in Nutanix, I don't have to buy any third-party software, because I have the data protection feature.
The third and most important feature is LCM, Life Cycle Management. With one click, I can upgrade my firmware as well as my software version, and there will be no downtime required for that. It is seamless.
