I have read through as much documentation as I can find, and I cant see an answer to this. MS say hosting of node.js is possible, but they don't seem to say what options, if any, there are for clustering and multi-region failover.
here I am assuming Azure can host node.js apps as a service, not just a VM were we have to install and manage our own node instances and manage clustering ourselves via kubernetes or similar. We don't want to have to touch kubernetes.
