I am aware that Azure supports UDP, but does it support UDP broadcast?
I am wanting to use the Jenkins Swarm plugin, which requires UDP broadcast for new slaves to join the master.

I woke this old thread up to add an update. Microsoft got this feedback through https://feedback.azure.com/forums/216843-virtual-machines/suggestions/400782-udp-endpoints and UDP support is added as shown below : Microsoft Azure VMs support UDP
Since i don't use Azure myself i cannot be 100% sure, but it seems it is not supported :
Is UDP broadcast available in Windows Azure virtual networks?
Unfortunately, broadcasts are not supported in Windows Azure.
Does Virtual Network support multicast or broadcast ?
No. We do not support multicast or broadcast.
