## JMS
JMS serves the frond end and handles communication between all components

JMS can be ran in difrent modes
### Scalable
 * Requires at least one external JMS to funcion
 * supports multiple external JVB/JIB hosts
 * Requires internal network for communication between servers

### Stand alone 
 * JMS with JVB 
 * supports multiple external JVB/JIB hosts
 * Requires internal network for communication between servers

### Full stand alone
 * Disable support external JVB/JIB hosts 
 * Does not requires a internal network
 * Running a JIB (even locally) requires config changes

 
## JVB
 * A meeting is server bound
 * Acts as load-balancing not fail-over
 * One JVB supports multiple meetings
 * Multiple JVB host can be connected to JMS (also if one is running on the JMS)

## JIB
 * One recording per server
 * Handles recording from the web UI (by moderator)
 * Multiple JIB host can be connected to JMS
 * Does not require open firewall ports
 * Needs at least 4CPU 4GB/Ram
