Create Composed Apps
This section describes how to create a composed app.
You can customize the services, workloads, and routes of an app to create a composed app. Compared to template-based apps, composed apps support app governance. You can enable app governance for a composed app to use traffic monitoring, grayscale release, and link tracing features.
Prerequisites
