One End-User Computer License allows access to a same-origin Application (same protocol, same host, and same port) to use the functionalities provided by the Software from one unique End-User Computer. 
2.3.2 Per Server License
One Server License is required to deploy the Application to one Server. Servers apply to both physical and virtual servers and include but are not limited to production servers all of which require licensing: failover servers, development servers that are also used for testing purposes, quality assurance servers, testing servers, and staging servers. Continuous integration servers (build servers) and localhost development servers don't require additional licenses. 
Per-server license is only for on-premises server deployment and is not applicable for cloud deployments. Please refer to section 2.4 below for applicable licensing if you are providing a cloud hosted/service application.
