Comparison is here: http://www.8bitavenue.com/2012/11/microkernel-vs-monolithic-os-architectures/ " -Service separation has the advantage that if one service (called a server) fails others can still work so reliability is the primary feature. For example if a device driver crashes does not cause the entire system to crash. Only that driver need to be restarted rather than having the entire system die. This means more persistence as one server can be substituted with another. It also means maintenance is easier. -Different services are built into special modules which can be loaded or unloaded when needed. Patches can be tested separately then swapped to take over on a production instance. -Message passing allows independent communication and allows extensibility -The fact that there is no need to reboot the kernel implies rapid test and development. -Easy and faster integration with 3d party modules."
