Why teams migrate from SQS to Pub/Sub
Good fit when
- +Teams migrating message queue workloads to GCP alongside compute migrations.
- +Applications that benefit from Pub/Sub's push delivery and global message ordering.
- +Teams wanting tighter integration with GCP event-driven services (Cloud Functions, Cloud Run).
Strengths
- Pub/Sub's push subscriptions simplify consumer architecture.
- Global message ordering and exactly-once delivery are built-in options.
- Native integration with Dataflow for stream processing and BigQuery for analytics.
Tradeoffs
- SQS FIFO queue semantics map to Pub/Sub ordering keys but with different guarantees.
- SQS visibility timeout pattern differs from Pub/Sub's ack deadline model.
- Dead-letter queue configuration and retry behavior differ between services.
Migration notes
- Map SQS queues to Pub/Sub topics and subscriptions.
- Translate SQS visibility timeout logic to Pub/Sub ack deadline configuration.
- Remap dead-letter queue configs to Pub/Sub dead-letter topics.
- Update consumer code from SQS polling to Pub/Sub push or pull subscriptions.
