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.
Typical effort:Medium (1-2 weeks)
