One of my customer called me today to ask what the difference was between vShieldApp and vShieldEdge, as they were looking at a competing firewall.
I paused for a minute because I could not explain it clearly, as Vmware’s website isn’t that clear about it either. I reached out to my trusted Vmware SME and he was able to explain the difference to me.
vShieldApp is a hypervisor based firewall (internal to cluster) – port based ACL functionality to isolate VM’s from each other.
vShieldEdge is a virtual firewall (internal cluster or to external world)
This is how VMWare explains it
(vShield-App is on the left, vShield-Edge is on the right)
Clear as mud ? This article will help explain further
