Event-Driven Madness: Azure Event Hub vs Azure Service Bus vs AWS SNS vs Google Pub/Sub
Feature Comparison
| Feature | Azure Event Hub | Azure Service Bus | AWS SNS | Google Pub/Sub |
|---|
| Best For | Real-time event streaming | Enterprise messaging | Pub/sub notifications | Scalable pub/sub |
| Ordering | No | Yes (FIFO) | No | Yes |
| Supports Transactions? | No | Yes | No | Yes |
| Message Retention | 1-7 days | 14+ days | Short-lived | 7 days |
| Supports Dead Letter Queue? | No | Yes | No | Yes |
| Throughput | Very High 🚀 | Medium | High | High |
| Latency | Low | Medium | Low | Low |
| Scalability | Insane | High | High | Auto-scales |

Final Thoughts
- Azure Event Hub: Great for real-time data ingestion, IoT, and big data pipelines.
- Azure Service Bus: Best for enterprise messaging, transactional workflows, and ordering guarantees.
- AWS SNS: Super simple pub/sub, integrates well with AWS Lambda, but not ideal for complex messaging.
- Google Cloud Pub/Sub: Scalable, reliable, and easy to use, perfect for cloud-native event-driven systems.
If you need real-time, high-throughput streaming, go with Azure Event Hub. If you’re on AWS and need pub/sub, SNS is your friend. And if you’re on GCP, just use Pub/Sub and call it a day. 😆
