VMware vCloud Director 1.0 Performance and Best Practices

As shown in Figure 17, when compared with deploying a vApp without fence mode, deploying a vApp with fence

mode takes a longer time. This is because vCloud Director needs to perform extra configuration in order to

deploy a vApp with fence mode. More detail is shown in Figure 18. Before powering on the vApp, vCloud Director

needs to deploy and configure a vShield Edge VM as the gateway, which takes more than 80 seconds.

If the vApp is deployed without fence mode, only the last two steps (reconfigure VMs and power them on) are

required.

Figure 18. Deploy a Single vApp with Fence Mode: Operation Breakdown

Figure 18 also shows that deploying vApps with an increasing number of VMs increases the deployment time

increases only slightly. This is because only one vShield Edge instance is required, even with multiple VMs in a

vApp.
