Quality of Service
Scalability

Scalability is vital as it ensures the service can handle increased data load or users without compromising performance.

Amazon EventBridge

No published metrics are available.

OneSignal

OneSignal can deliver a throughput of over 850,000 notifications per second, which relatively equates to 4 billion push notifications daily. It has also been able to scale its database to 75 terabytes (TB) of stored data across nearly 40 servers.

Amazon EventBridge

Yes

Amazon EventBridge promises at-least-once event delivery. It will try to deliver an event to a target for up to 24 hours.

OneSignal

No

OneSignal does not guarantee message delivery. It only offers confirmed deliveries. That means it does not handle retries in the event of failures, and the message may not be delivered.

Guaranteed message ordering

Maintains the sequence of messages as they were sent. This is particularly important in apps where the chronological order of messages is essential for meaningful communication.

Amazon EventBridge

No

OneSignal

No

Exactly-once message delivery

Guarantees that each message is processed exactly once, preventing data inconsistencies that can arise from duplicate processing or missing messages.

Amazon EventBridge

No

Amazon EventBridge does not support exactly-once delivery semantics out of the box. It ensures at least-once delivery, but does not guarantee exactly-once delivery.

OneSignal

No

Global edge network

By bringing servers (Points of Presence, or PoP) geographically closer to the devices of end users, and routing requests to the nearest PoP, global latency is reduced to a minimum.

Amazon EventBridge

Yes

OneSignal

No

Multi-region data replication (message durability)

By replicating data across multiple regions, the risk of data loss or downtime is greatly mitigated since if data is lost or a server fails in one region, the information can be retrieved from another.

Amazon EventBridge

No

OneSignal

No

OneSignal locates its datacenters in the EU, and it's unclear if they support multi-region data replication.
