# Components

The Appliance Server automatically installs several components for the operation of HPE Morpheus Enterprise. This includes:

- RabbitMQ (Messaging)
- MySQL (Logistical Data store)
- Opensearch (Logs / Metrics store)
- Tomcat (HPE Morpheus Enterprise Application)
- Nginx (Web frontend)
- Guacamole (Remote console service for clientless remote console)
- Check Server (Monitoring Agent for custom checks added via UI)

All of these are installed in an isolated way using chef zero to `/opt/morpheus`. It is also important to note these services can be offloaded to separate servers or clusters as desired. For details check the installation section and high availability.
