Quality of Service
Scalability

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

Google Cloud Run

In Cloud Run, each revision automatically scales to the necessary number of instances to handle incoming requests, events, or CPU utilization, and scales down to zero instances when there is no traffic.

Pusher

No scalability metrics published.

Guaranteed message delivery

Ensures messages are never lost during transmission, even in the presence of network disruptions.

Google Cloud Run

No

Cloud Run doesn't guarantee message deliverability as it can scale to zero instances when traffic drops, interrupting WebSocket connections.

Pusher

No

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.

Google Cloud Run

No

Cloud Run doesn't guarantee message ordering for WebSockets, as multiple instances may handle connections independently.

Pusher

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.

Google Cloud Run

No

Cloud Run doesn't provide exactly-once message delivery semantics for WebSockets, as it lacks built-in deduplication and can't guarantee single processing of messages across scaling events or instance changes.

Pusher

No

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.

Google Cloud Run

99.95%

Pusher

Channels SLA: API will be made available with an Annual API Uptime Percentage of 99.95%.

Pusher will use commercially reasonable efforts to make Pusher Beams available with an Annual Uptime Percentage of > 99.95%.

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.

Google Cloud Run

No

Cloud Run is typically deployed in specific regions, and WebSocket connections are established directly to those regional endpoints.

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.

Google Cloud Run

Yes

Cloud Run services are automatically distributed across multiple zones within their deployed region, enhancing availability and fault tolerance without requiring manual configuration.

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.

Google Cloud Run

Yes

Cloud Run eliminates single points of failure through multi-zone deployment, automatic load balancing, and auto-scaling.

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.

Google Cloud Run

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.

Security & compliance
API key authentication

Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens.

Google Cloud Run
Pusher

Yes

Token-based authentication

Provides a means to securely authenticate user devices against your user management system.
