We have built a brand new user interface for Azure Policy that enables you to manage policies easily across all your subscriptions in a single place. In addition, you are able to continuously monitor compliance status of all your resources. This is very useful when you have a lot of resources that existed before you applied the policy. You can easily group your policies and look for the non-compliant resources. The policy engine constantly evaluates your resources and updates the compliance status. It also provides historical data in the dashboard. API support for historical data will be added in the future. In addition, the new UI supports a much richer set of policy management features, such as the creation of a custom policy. You can refer to thisguidefor new information.
