Pricing | |||
Free plan | With a free plan, you can test the service’s functionality and compatibility with your project before committing to a paid plan. | Google Cloud Run Yes | PubNub Yes |
Pricing model | The pricing model should align with your project's expected load, usage patterns, and budget in order to be cost-effective and efficient. | Google Cloud Run Cloud Run has a free tier and two paid tiers of usage-based pricing, based the number of CPUs, memory, and requests used. Read more | PubNub PubNub offers Free, Starter, and Pro packages. Their support packages, separate from their standard plans, also include an Enterprise option. Their pricing model is based on monthly active users (MAUs). See the pricing page |
Integrations & interoperability | |||
SDKs | Supporting multiple languages and platforms offers greater flexibility when building cross-platform realtime apps. | Google Cloud Run
| PubNub

Supported realtime protocols | Support for multiple protocols provides the flexibility to choose a protocol that best suits your project’s requirements. | Google Cloud Run
| PubNub
PubNub uses HTTP as the transport for their client libraries. A WebSocket compliant interface is provided in some libraries, however this is just a wrapper around an underlying HTTP transport. |
Serverless functions | Enables integration with third-party cloud providers by facilitating the execution of custom code against messages to perform business logic like on-the-fly translation. | Google Cloud Run
| PubNub
PubNub allows you to run code on its own platform using proprietary PubNub Functions in the form of “Blocks”. The code you can run in Blocks is limited to the Javascript API available in PubNub’s system. |
Streaming & queueing | Provides a dependable method to reroute messages from the service to third-party streams and queues for further processing. | Google Cloud Run Yes | PubNub Egress:

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. | PubNub

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. | PubNub 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. | PubNub 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. | PubNub 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% Read more | PubNub 99.999% |
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. | PubNub Yes |
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. | PubNub Yes |
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. | PubNub Yes |
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. | PubNub <100 milliseconds delivery |
Security & compliance | |||
API key authentication | Simplifies the authentication code on trusted servers compared to requesting, managing, and refreshing tokens. | Google Cloud Run Yes Read more | PubNub No PubNub does not provide configurable private key permissions. It uses a different model where each client’s access is configured with the PubNub Access Manager (PAM). |
Token-based authentication | Provides a means to securely authenticate user devices against your user management system. | Google Cloud Run No | PubNub Yes |
Single Sign-On (SSO) authentication | SSO streamlines login processes, boosts security by minimizing password use, and meets compliance needs for secure data access management. | Google Cloud Run | PubNub Yes Google and SSO |
Rules for permissions and operations | Provides control over which users can subscribe and publish to certain channels. | Google Cloud Run Yes | PubNub |
End-to-end encryption | Ensures that the data transmitted between the client and the API server remains confidential and secure while in transit. | Google Cloud Run Yes | PubNub Yes All customer data stored within PubNub is encrypted in transit over public networks using TLS 1.2+. Customer data stored in PubNub cloud products and services is AES-256 encrypted at rest. |
