Pivotal GemFire licensing is obtained and managed through your Pivotal account manager. You do not need to install physical licenses to run Pivotal GemFire, unless you opt to use vFabric License Server to manage your GemFire licenses on VMware vSphere virtual machines.
For evaluation purposes, you can download and try out Pivotal GemFire at any time. This download includes Pivotal GemFire's full feature set and supports client/server (unlimited clients) and multi-site (WAN) deployment topologies.
To learn more about purchasing appropriate Pivotal GemFire licensing for use in a production environment, please see http://www.gopivotal.com/big-data/pivotal-gemfire or contact your Pivotal account manager.
If you are running Pivotal GemFire on vSphere VMs, you can choose to use vFabric License Server to manage GemFire licenses in order to ensure physical host redundancy. To read about using vFabric License Server with GemFire deployments on VMware vSphere, see Improving GemFire Performance on vSphere.
