Here’s a neat trick for AEM developers and architects: you can create a diagram representation of the service dependencies using Composum. For those not familiar, Composum is an Open-Source project based on Apache Sling.
To create a service dependency diagram, you will need to install two additional dependencies:
Once you install the dependencies, you can access the Composum Service Graph web console at /system/console/servicegraph.
Using the Service Graph Web Console
Digitizing the Healthcare and Patient Experience
Find out how more than 100 healthcare executives and their respective organizations are modernizing patient and customer experiences.
The Service Graph Web Console has a couple fields, the most important being the Classnames Regex. You can put any regular expression to filter what classes should be including:
Every OSGi Service matching the regular expression will be included in the graph. Note that having too broad of a regular expression, such as ^com.adobe or ^org will cause the graph to fail to render, so make sure to narrow down as much as possible.

I’ve also created an issue with the Composum team to include this in their next release.
