Pusher will use commercially reasonable efforts to make Pusher Beams available with an Annual Uptime Percentage of > 99.95%. Read more |
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. | Firebase Yes Firebase benefits from Google's global edge network. | Pusher 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. | Firebase No Multi-region data replication is currently not supported in Firebase Realtime Database, but it is supported in Firestore databases. | Pusher No Pusher apps are located in a single data center rather than distributed across multiple data centers. Any latency issues that occur in that data center will affect all apps hosted there. |
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. | Firebase No Each Realtime Database instance is tied to a single region chosen at the time of creation. | Pusher No Pusher apps are located in a single data center rather than distributed across multiple data centers. If that data center goes offline then all apps hosted there are affected. |
Latency | Low latency is crucial for realtime apps as it ensures swift and efficient data transmissions, providing a smoother and more responsive user experience. | Firebase Unknown. | Pusher Not shared. Because apps exist in only one region, message latencies increase for clients the further they are from your chosen data center. |
