The IIS will takes the entire responsibility when host the WCF service through iis. We don't need to write any code for this things like process hosting idle time management process recycling and etc. But when host the application through self hosting we need do the code to this.

IIS will load your service on demand i.e. when a first request is received then it will create a servicehost and then servicehost creates service class to handle the request. This is beneficial in managing the system resources. If not needed the memory of the system is not consumed. IIS also handles the lifetime of the service like activating recycling and so on. But you are dependent on the IIS for recycling the apppools when needed and for any critical scenarios. Selfhosting gives you full control like when to start a service host stop and so on. But you need to recycle the service and have to programmatically handle all the required things to make your service to work in critical errors. Sometimes it may lead to server crash.
