Virtual machine components using Red Hat OpenShift with VMware vSphere concepts
This resource will help you better understand the individual components and settings included within virtual machines (VM) as it relates to both Red Hat® OpenShift® and VMware vSphere. As virtual machine components in OpenShift can be found within the virtual machines themselves, there is no menu mapping chart for this comparison portion.
What will you learn?
- How OpenShift menu and features map to ones you may know from VMware
What do you need before starting?
- VMware vSphere 8.0 or higher (as referenced in this path)
- Red Hat OpenShift (as referenced in this path)
Virtual machine feature mapping chart
This section addresses commonly used VM functions in VMware and how they map to OpenShift.
