You know the feeling. A job finishes in Cloud Run, and now you need to tell something else about it — maybe another service, maybe the audit logs. AWS SQS and SNS feel like the obvious answer, but wiring them together with Cloud Run can make even calm engineers mutter things that would cost them a code of conduct warning.
Here’s the fix. AWS SQS/SNS Cloud Run integration gives you a clean messaging bridge between Google Cloud and AWS workloads. SQS queues handle durability, SNS topics fan out events, and Cloud Run containers deliver the logic. Together, they decouple systems that used to choke on synchronous APIs or security bottlenecks.
The idea is simple: Cloud Run publishes or consumes events from SNS and SQS through authenticated endpoints. Messages leave AWS with signed requests, hit your Cloud Run endpoint secured by OAuth or an identity proxy, and the container handles whatever workflow follows. It might trigger a downstream job, write an audit entry, or call another internal service. Everything stays async, observable, and properly isolated.
To integrate, authenticate your Cloud Run service account with temporary credentials using AWS IAM’s OIDC federation. It means Cloud Run can call AWS resources directly without static keys. The reverse works too, using AWS IAM Roles Anywhere or STS to send signed requests into Cloud Run. Your network perimeter is now identity-based instead of IP-based, which is exactly where you want to be.
When debugging, look first at IAM permissions rather than payload formatting. Most “queue not found” or “unauthorized” errors boil down to mismatched roles or expired trust configurations. Add structured logging around message receipt timestamps, and your SREs will thank you later.
