Virtual services are critical resources of Service Mesh (ASM) instances for traffic routing. A virtual service defines a set of rules for routing traffic to destinations. Each routing rule defines traffic matching criteria. If traffic matches the criteria in a routing rule, traffic is forwarded to the destination service or a version (subset) of the destination service specified in the routing rule. This topic describes how to create, modify, and delete a virtual service.
