Difference between AOS , Foundation and Hyervisor | Nutanix Community
Skip to main content
Hello Experts,



I am new to Nutanix world and in middle of acquiring basic knowledge. In Prism console under software upgrade, i can see that there are components like AOS , Foundation and Hypervisor.



My understanding is that the Acropolis ( AOS ) software is installed in CVM and CVM is called as Foundation. Hypervisor is either AHV or Vmware or HyperV.



Is my understanding is correct ? Please clarrify



Thanks

Sam.
Hi @Saleemmek;



Welcome to the Nutanix world and your understand is almost correct. AOS (formerly NOS) is the Acropolis Operating System and is the base operating system that runs on each CVM.



The Foundation is a tool used in field to perform cluster creation and imaging bare metal nodes. The Foundation is also built in to the CVMs and in that case, can also be used to perform cluster expansion and by some workflows like LCM (Life Cycle Manager) firmware upgrades. Keep in mind that you can perform Foundation upgrades independently of AOS upgrades to take advantage of new features.



About hypervisor, Nutanix support AHV (Acropolis HyperVisor), which is the Nutanix free hypervisor, Microsoft Hyper-V, VMware vSphere ESXi and Citrix XenServer.
Thanks @RichardsonPorto for your answers. It is clear now.



Cheers

Sam.
