Did you know? Azure web sites can be configured to auto-heal

Recently, Microsoft added a new, very useful feature to Azure web sites: auto-healing. Auto-healing in Azure builds on the older, on-premises IIS features for application pool recycling: restarting the application pool after a number of requests, error conditions or more.

In Azure, you can also monitor slow requests and HTTP status codes. For instance, you can restart the site when an HTTP 500 Internal Server error occurs.
