+= Splitting traffic between revisions using the Developer perspective
+
+After you create a serverless application, the serverless application is displayed in the *Topology* view of the *Developer* perspective. The application revision is represented by the node and the serverless resource service is indicated by a quadrilateral around the node.
+
+Any new change in the code or the service configuration triggers a revision, a snapshot of the code at a given time. For a service, you can manage the traffic between the revisions of the service by splitting and routing it to the different revisions as required.
+
+.Procedure
+To split traffic between multiple revisions of an application in the *Topology* view:
+
+. Click the serverless resource service, indicated by the quadrilateral, to see its overview in the side panel.
+. Click the *Resources* tab, to see a list of *Revisions* and *Routes* for the service.
++
+image::odc-serverless-app.png[Serverless Application]
+
+. Click the service, indicated by the *S* icon at the top of the side panel, to see an overview of the service details.
+. Click the *YAML* tab and modify the service configuration in the YAML editor, and click *Save*. For example, change the `timeoutseconds` from 300 to 301 . This change in the configuration triggers a new revision. In the *Topology* view, the latest revision is displayed and the *Resources* tab for the service now displays the two revisions.
+. In the *Resources* tab, click the btn:[Set Traffic Distribution] button to see the traffic distribution dialog box:
+.. Add the split traffic percentage portion for the two revisions in the *Splits* field.
+.. Add tags to create custom URLs for the two revisions.
+.. Click *Save* to see two nodes representing the two revisions in the Topology view.
