Resilience for WCF service hosted as windows service.

Question

We have got WCF services one hosted as windows service (it uses MSMQ binding) and other hosted in IIS. To have resilience we have got 7 servers where WCF is hosted on IIS, and the 3rd party tool randomly sends request to either of the servers.

How to achieve a similar functionality for WCF service hosted on windows service using MSMQ binding.

Answer 1

If your 3rd Party tool also 'works' like NLB by itself having an additional IP and then randomly picking one of the clustered IPs then the below article should help:

(Note that if you are using private$ queues then only one of the servers will actually receive the message, which should be correct)

Alternatively, you might look at using a (single) remote queue on a server and then find another way to manage the redundancy of the MSMQ storage?

HTH!
