EnSync vs. Cloud Message Queues (SQS / Google Pub/Sub)
| Criteria | SQS / Google Pub/Sub | EnSync |
|---|---|---|
| Primary Use Case | Internal async messaging between microservices | B2B partner ecosystem integration |
| Target Audience | Your internal engineering team | External partners + your team |
| Partner Onboarding | N/A (not designed for external partners) | Self-service via developer portal |
| Access Control | IAM policies (cloud account level) | Workspace isolation per partner |
| Message Retention | 14 days max (SQS), 7 days default (Pub/Sub) | Up to 30 days (plan-based) |
| Replay Capability | No native replay | Built-in replay (up to 30 days) |
| Message Ordering | FIFO queues (limited throughput) | Ordered delivery per event type |
| Schema Management | No schema enforcement | Structured events with versioning |
| Partner Visibility | CloudWatch/Stackdriver (your account only) | Per-partner observability dashboard |
| Bidirectional Communication | Requires separate queues | Native bidirectional events |
| Multi-Tenancy | Requires separate AWS/GCP accounts | Targeted delivery + workspace isolation |
| Event Naming | Queue names (flat structure) | Path-like hierarchy (payment/authorized) |
| Best For | Internal microservices communication | External partner integrations |
| Partner Self-Service | N/A | Embedded developer portal |
| Compliance/Audit | CloudTrail/Cloud Logging (your view only) | Full audit trails per partner |
Bottom Line
SQS/Pub/Sub broadcasts to all subscribers. EnSync delivers to specific partners. SQS/Pub/Sub connects your microservices. EnSync connects your business partners.When to Choose SQS/Pub/Sub
- You need internal microservices messaging within your own infrastructure
- You’re building internal message-driven architecture for your own services
- All consumers are within your AWS/GCP account
When to Choose EnSync
- You’re integrating with external business partners
- You need targeted event delivery (not broadcast to all)
- You need high throughput for partner integration workloads
- You need partner-specific isolation and visibility
- You want partners to self-manage via developer portal
- You need long-term message retention and replay
- You need two-layer access control (permissions + subscriptions)
While EnSync can be used for internal messaging, our focus is on B2B partner integration where workspace isolation, partner observability, and self-service developer portals provide the most value.
