You are managing a customer-facing web application deployed on Cloud Run. The development team has created a new version of the application with a redesigned UI. The product manager wants to test the new UI with 10% of the live user traffic to ensure it doesn't negatively impact conversion rates before rolling it out to everyone. How should you implement this?

Deploy the new version to a separate Cloud Run service and configure Cloud DNS to route 10% of requests to the new URL.

Deploy the new version to the existing Cloud Run service and use the traffic splitting feature to route 10% of traffic to the new revision.

Modify the application code to randomly serve the new UI to 10% of users.

Use Cloud Load Balancing to route traffic based on the user's geographic location.
