This is a virtualization introduction and when you should be using it. In the follow-up videos, I will go into using the hypervisor, creating VMs and maintenance.
Now that you understand what it is and if you want to start getting your feet wet, please check out my other video to start installing your hypervisor and launching your first virtual machine here. I highly recommend starting out with VMware as it used the most. It also has the most material online if looking for virtualization introduction videos and how to guides.
I live stream on Twitch and encourage you to drop in and ask a question. I regularly publish on YouTube and christitus.com, but if you need immediate assistance, check out our discord channel at Chris Titus Tech Discord.
