|
Guaranteed message delivery | Ensures messages are never lost during transmission, even in the presence of network disruptions. | AWS AppSync No | Twilio Yes While Twilio ensures reliable delivery, it typically follows at-least-once or best-effort delivery models. That means messages may be delivered more than once in rare cases, such as during network failures or retry attempts. |
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. | AWS AppSync No | Twilio No Twilio sends SMS messages in the order they are queued, but they are delivered individually. That means that if you send multiple SMS messages to the same user quickly, Twilio cannot guarantee that the messages will arrive in the order you sent them. Read more |
Exactly-once message delivery | Guarantees that each message is processed exactly once, preventing data inconsistencies that can arise from duplicate processing or missing messages. | AWS AppSync No | Twilio No Twilio doesn't guarantee exactly-once delivery by default. However, it can implement de-duplication in the receiving service by checking if an event with the same ID has already been received, and discarding duplicates. Read more |
| Performance & availability | |||
Uptime Guarantee | An uptime guarantee instills confidence in the reliability of the service and protects your business from the negative impacts of downtime. | AWS AppSync 99.95 uptime SLA | Twilio
|
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. | AWS AppSync No | Twilio Yes Twilio has a global edge network of network edges called Twilio Edge Locations, which allows you to control the geographic location where your application's network traffic enters and exits Twilio's platform. |
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. | AWS AppSync Partial Single region by default - multi region deployment of AWS AppSync would require integration of Amazon DynamoDB Global Tables. | Twilio Yes Twilio provides multi-region data replication to enhance message durability. |
No single point of failure or congestion | Having no single point of failure means a system is resilient and can continue to operate even if one part fails. Avoiding a single point of congestion ensures messages flow efficiently across the system and avoids bottlenecks that could lead to performance issues under load. | AWS AppSync Partial Not available by default - but could be built with the integration of Amazon DynamoDB Global Tables. | Twilio Yes Twilio's "Super Network" and hybrid cloud infrastructure reduce the risk of a single point of failure and congestion. The design is built with redundancy and scalability to minimize potential disruptions. |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | AWS AppSync Unknown, although reports in forums suggest it is 200-500 ms. | Twilio Unknown. |
