| Aspect | Azure Event Grid | AWS EventBridge | Google Cloud Eventarc |
|---|---|---|---|
| Starting price model | Usage-based: per-operation and capacity-tiered options; region- and agreement-dependent (published pricing varies) | Usage-based: published per-volume pricing examples and payload chunking rules for certain categories | Usage-based: editioned tiers with published per-volume message pricing and pipeline charges; event sizing rules affect billing |
| Primary use case | Azure-native event routing for discrete events; integration with serverless handlers | AWS-native event bus routing between AWS services and SaaS partners | GCP-native routing to services such as Cloud Run, with audit-log/eventing integration |
| Key strength | Integration with Azure services and serverless tooling; managed pub/sub for discrete events and fan-out patterns | Broad AWS service integration and mature AWS eventing patterns | Integration with GCP services and explicit pipeline/receiver models |
| Key weakness | Can be confusing relative to Event Hubs/Service Bus; operational troubleshooting and private networking complexity | Costs can grow with volume and payload chunking; multiple components can complicate cost modeling | Edition complexity and additional costs for receivers/observability; event sizing rules affect billing |
