Cloud-based VE License Server Overview

The following image provides an overview of a sample VE license server topology in a cloud environment (with the Charon-SSP VE emulator product):

Points to note:

• The license server software can be combined with the matching Charon -SSP emulator software on one instance, or it can run on a separate system.
• The license server must be installed in a supported cloud environment.
• Charon host and license server do not need a public IP address. They communicate across the cloud-internal LAN environment.
• Starting with Charon-SSP version 4.1.19, a backup license server is supported.

The decision whether the license server should run on a separate instance depends on the customer's requirements.

VMware-based VE License Server Overview

The following images provides an overview of sample VE license server topologies in a VMware environment.

...

1. The license server binds to the ESXi host on which the license server host runs.
2. The license server binds to the vCenter manager that manages the ESXi host on which the license server host VM runs.

VE License Server Binding with ESXi Host

The following image illustrates a topology where the VE license server binds to the ESXi host on which the VM with the license server runs (with the Charon-SSP VE emulator product). It shows one VM with license server and emulator software and another VM on the same ESXi host (not mandatory) with the emulator software configured to use the license server via the network.

...

Please note: vMotion of a VM in which the VE license server runs to a different ESXi server is only possible if binding to a vCenter server (see below) is used. vMotion of a license server VM when binding to the ESXi server will invalidate the installed licenses.

VE License Server Binding with vCenter Server

The following image illustrates a topology where the VE license server binds to the vCenter Server managing the ESXi host on which the VM with the license server runs. It shows one VM with license server and several other VMs using the license server across the network.
