Azure Portal Service passes service package to “Red Dog Front End” (RDFE).
RDFE converts service package to native “RD” version. RDFE sends service to Fabric Controller (FC) based on target region.
FC queues request in repository, than deploys and activates service.
XLS –Xlocation
Xlocation redirects the request to a particular datacenter as per the user’s initial selection.
It has a mapping table which correlates requests and the corresponding datacenter.
For example if an application needs to be deployed in US South West, then XLS will redirect it to Chicago Datacenter
