Cloud Service Mesh lets you enable mesh advanced traffic management capabilities, such as weighted traffic splitting and global load balancing, as well as observability and security policies for traffic from one Cloud Run service to another. It also gives you a fully managed data plane solution that removes the operational burden of maintaining your own service mesh sidecars.
For instructions on how to configure Cloud Run services that use Cloud Service Mesh to run on a range of computing infrastructures, see Configure Cloud Service Mesh for Cloud Run.
