Azure Resource Manager (ARM)

Azure Resource Manager templates ARM templates can: o o Simplify deployment Simplify roll-back Provide cross-resource configuration and update support Be used as a learning tool to build to suit Azure templates are: o o o Depends on SQL Source file, checked-in Specifies resources and dependencies (VMs, websites, DBs) and connections (configuration, LB sets) Configurable parameters for input/output SQL configuration DEPENDS ON Depends on.
