= System Requirements These are the requirements to run the {{book.project.name}} authentication server: * Can run on any operating system that runs Java * Java 8 JDK * zip or gzip and tar * Network multicast support if you are clustering {{book.project.name}}. * At least 512M of RAM * At least 1G of diskspace {{book.project.name}} can be clustered without multicast, but this requires a bunch of configuration changes. Please see the <<../clustering.adoc#,clustering>> section of this guide for more information.
