Azure Virtual Network Manager rule impact
analyzer is now generally available, empowering you
to simulate the impact of your security admin rules on your virtual
networks before deploying your rules.
With this capability, you
can simulate the effects of your security admin rules on
your virtual networks’ existing traffic
flows and modify rules as needed to ensure your
desired traffic flows are maintained and reduce the risk of
unexpected connectivity issues.
This feature is available in the Azure portal
and is powered by Azure Network Watcher traffic analytics
and virtual network flow logs, providing data-driven
insights into how security admin rule deployments could
affect your existing virtual network traffic.
