vShield Zones – Some Serious Gotchas
OK..I’ll admit it: I am spoiled by the capabilities of vSphere. What other platform lets you schedule system updates that will occur unattended and without outages of the applications being used?

Rather than regurgitate how it works, take a look at Rodney’s excellent post. A customer has decided to use vShield Zones to help with PCI Compliance. The desire is that only certain VMs will be allowed to communicate with certain other VMs using specific network ports, and to audit that traffic. ’nuff said.
