I recently read the guide titled “Manage the Availability of Virtual Machines” http://www.windowsazure.com/en-us/manage/windows/common-tasks/manage-vm-availability/– which all sounds good. However, I cannot find information anywhere that describes how the two or more Virtual Machines in a Cloud Service, each part of the same availability set, will synchronize data with each other.
For example, if I update a database file on VM1, how is this file updated on VM2? Can someone please explain this?
Is the sync automatic and if so, how are data sync conflicts handled?
