Quality of Service
Scalability

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

AWS AppSync

No published metrics are available. However, this works on top of serverless technology which means theoretically it should scale to millions of concurrent connection with little to no tuning from the customer.

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.

Guaranteed message delivery

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

AWS AppSync

No

Google Cloud Run

No

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

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

Google Cloud Run

No

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

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

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.

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

Google Cloud Run

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.

AWS AppSync

No

Google Cloud Run

No

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

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.

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.

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.

Google Cloud Run

Yes

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

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.

Google Cloud Run

Unknown.
