The recommendations are divided into 5 categories

1. Reliability

   • used to ensure and improve the continuity of business critical applications

2. Security

   • detect threats and vulnerabilitites that might lead to security breaches

3. Performance

Azure Service Health

It helps you keep track of azure resources, both your specifically deployed resources and the overall status of azure.

Azure service health does this by combining three different azure services

   • informs you the service outages in azure on the azure status page

   • This page is view of the health og all azure services across all azure regions.

2. Service health

   • provides narrow view of azure services and regions.

   • this is the place to look for service impacting communications about outages, planned maintenance activities and other health advisories because the authenticated service health experience knows which services and resources you currently use.

3. Resource Health

   • Tailored view of your actual azure resources.

   • provides information about the health of your individual cloud resources, such as a specific VM instance.

Historical alerts are also stored and are accessible for later review
