With the introduction of SDL Web 8, publishing has changed. Overall, once you get your head around it, Topologies (the new way of publishing) are a nice approach. They provide a clear separation between the Content Management and Content Delivery environments.

- On the Content Management server browse to %TRIDION_HOME%\web\WebUI\Editors\CME\Configuration\
- Open the CME.config file
- Find enablepublishingmanagement and change the value to true
- Restart the Content Manager website
- Within the Content Manager the Publishing node will be back
