| SignalR Client SDKs:
Server SDKs:
|
Supported realtime protocols | Support for multiple protocols provides the flexibility to choose a protocol that best suits your project’s requirements. | Google Cloud Pub/Sub None. Google Pub/Sub does not natively support any real-time protocols. However, you can implement WebSockets using other Google services like Google's Compute Engine. | SignalR
|
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 Pub/Sub
