Your team is preparing to launch a new API in Cloud Run.

Comprehensive and Detailed Explanation:

Cloud Run scales down to zero when idle. If CPU is allocated only during request processing, background telemetry tasks (like OpenTelemetry traces) may not complete before the container shuts down.

Solution: Configure CPU to be always-allocated → This ensures that background tasks (like trace exports) continue even when the service is idle.

????Why not other options?

A (Increasing CPU to 4 cores)❌→ More CPU won’t help if traces are being cut off due to shutdown.

B (Using an HTTP health check)❌→ Doesn’t affect OpenTelemetry traces.

C (CPU only during request processing)❌→ This causes the problem because traces need CPU after request completion to be exported.
