Zephyr Server Requirements

Zephyr must run in an isolated instance where there is no Jira running or any other Tomcat.

Zephyr should only be installed on its' own server. If you are running a Jira instance, it should be installed on a different server.
We recommend you to have Zephyr installed on a separate instance from where you have your Jira/Tomcat installed.
