Azure Policy contributes to resource governance primarily through enforcing compliance with organizational standards and requirements. It does this by assessing the state of your resources and configurations for compliance with business rules and industry standards.

Here's a step-by-step explanation:

1. Define Policies: Azure Policy allows you to create policies that enforce rules and effects over your resources. These policies could be related to naming conventions, allowed locations, required tags, and more.

2. Assign Policies: Once the policies are defined, they can be assigned to any scope of resources such as management groups, subscriptions, resource groups, or individual resources.

3. Evaluate Compliance: Azure Policy evaluates your resources for non-compliance with the assigned policies. If a resource is found to be non-compliant, it is marked as such in the compliance blade of the Azure Policy.

4. Remediate Non-Compliance: Some policies have the ability to not just audit for non-compliance, but also to fix it. This is done through the 'DeployIfNotExists' and 'Modify' effects in the policy definition.

5. Monitor Compliance: Azure Policy provides a compliance summary that shows the compliance state of the resources. This helps in monitoring the overall compliance of your resources.

So, while Azure Policy does not directly monitor resource performance, provide customer support, or manage Azure subscription costs, it plays a crucial role in maintaining compliance and standardization across your Azure resources, which indirectly helps in better resource management and cost optimization.
