## Ensure reliable outbound connectivity with VNet NAT

Using default outbound connecitivty provided by a Standard Load Balancer or other Azure resources is not recommended for production workloads as this causes connection failures (also called SNAT port exhaustion). The recommended approach is using a VNet NAT which will prevent any failures of connectivity in this regard. NAT can scale seamlessly to ensure your application is never out ports.

Virtual machines that don't have replication enabled to another region aren't resilient to regional outages. Replicating virtual machines reduces any adverse business impact during Azure region outages. Advisor detects VMs on which replication isn't enabled and recommends enabling it. When you enable replication, if there's an outage, you can quickly bring up your virtual machines in a remote Azure region.

## Do not override hostname to ensure website integrity
116
-
Advisor recommend to try avoid overriding the hostname when configuring Application Gateway. Having a different domain on the frontend of Application Gateway than the one which is used to access the backend can potentially lead to cookies or redirect URLs being broken. Note that this might not be the case in all situations and that certain categories of backends (like REST API's) in general are less sensitive to this. Please make sure the backend is able to deal with this or update the Application Gateway configuration so the hostname does not need to be overwritten towards the backend. When used with App Service, attach a custom domain name to the Web App and avoid use of the `*.azurewebsites.net` host name towards the backend. [Learn more about custom domain](../application-gateway/troubleshoot-app-service-redirection-app-service-url.md).
