Does anyone know if there is a service out there that can be used as a file share witness for a Windows Server 2008 R2 Failover Cluster File share witness?
I have a two-node cluster but no good place for my file share witness - can I use the cloud?
Edit: I feel I should add some qualification to this question as it seems to have struck a nerve as several people think it is a very bad idea. Whether or not this is a good idea was not really the question as I did not provide sufficient detail of the environment for you to make such a judgement. For the benefit of others who may come across this thread, this is quite definitely not a good idea for most classic cluster installations. In the case of geographically dispersed clusters or clusters that otherwise depend on the internet in any event, this could be a compelling option if it is otherwise difficult to find a suitable location for your FSW.
As far as the general importance of the FSW goes, and what would happen if you lose connectivity to it, the answer is "not much" - as a critical component of your cluster goes, it is probably the least critical. In order for there to be any impact at all other than a few errors, at least one more component of your cluster would have to fail. I was actually innaccurate in a comment below - in this state you can failover - just not automatically. Don't get me wrong - you are definitely in a degraded state, and you don't want to be here for long or very often, but depending on your definition of "very bad things" - this would not qualify in my opinion.
The bottom line is that this might be a good idea in very specific circumstances. I marked JohnThePro's answer although I have not been able to verify whether it will work.
