## Question

You need to ensure that the solution can meet the scaling requirements for Policy Service.
Which Azure Application Insights data model should you use?

## Correct Answer

_See scenario._

## Explanation

Application Insights provides three additional data types for custom telemetry:
Trace - used either directly, or through an adapter to implement diagnostics logging using an instrumentation framework that is familiar to you, such as Log4Net or
System.Diagnostics.
Event - typically used to capture user interaction with your service, to analyze usage patterns.
Metric - used to report periodic scalar measurements.
Scenario:
Policy service must use Application Insights to automatically scale with the number of policy actions that it is performing.
