Why did you start using ESXI, what for?
Fortunately, one of my senior colleagues in my team just got me an opportunity to set up a server for hosting some web applications. The server machine has got quite a good specs including i7–7700K 4CPUs with 4.20GHz capacity, and 16G memory.
As my part leader and I have been planning to have multiple OS instances running for multiple web applications, after some googling I figured out how to host multiple instances within a single machine.
Typically, as far as I know, software geeks have been indulged in using virtual box to install different kinds of Operating System, but I think it ended up giving away its position to Hypervisor because Hypervisor doesnt’ need any operating system to serve another OS to install Virtual Box and then install other OS repeatedly.
Hypervisor has got rid of one step of OS installation. On the host machine, just install the Hypervisor and then create VM whenever you want then run it and that it.
Hypervisor is defined as a logical platform to run multiple Operating System in one single computer.
It’s going to look just like this

the ESXI has been produced by VMWARE.
VMWARE provides public license for ESXI 6.5 version. I have downloaded the installer for my host machine and then made a booting USB for startup. I will share the rest of process for further steps.
