Cloud Run gets WebSockets, HTTP-2 and gRPC bidirectional streams | Google Cloud Blog
"new traffic serving capabilities for Cloud Run: end-to-end HTTP/2 connections, WebSockets support, and gRPC bidirectional streaming, completing the types of RPCs that are offered by gRPC. With these capabilities, you can deploy new kinds of applications to Cloud Run that were not previously supported, while taking advantage of serverless infrastructure. These features are now available in public preview for all Cloud Run locations."
"Lambda has supported runtimes for multiple languages such as JavaScript (Node.js), Java, Python, and Go and supports custom runtimes as well, whereas Cloud Run uses standard OCI images (commonly known as Docker images). Existing applications that are stateless and containerized should be deployable to Cloud Run as is."
