Our Sitecore CM (PAAS hosting) handles a lot of traffic. We plan to cater to this traffic with multiple web apps in Azure.

I am unable to figure out the following:

On the Publish:End:Remote event, Sitecore purges the cache. In my case, we have multiple CMs. So how will it purge the cache on all instances?

Or should we write code to override the default functionality and provide all the arguments programmatically?
