The main reason, why gRPC support is not available for App Engine flexible environment as yet, is related to the presence of the load balancer. In fact one may say that gRPC would be supported, were it not for the fact that the GAE load balancer prevents such requests to reach the instances.
Engineers are keenly aware of the need to provide GAE access for gRPC requests, and actively working to implement such access. For the time being, your can use Compute Engine instances sitting behind a network load balancer <https://cloud.google.com/compute/docs/load-balancing/network/> with an autoscaler <https://cloud.google.com/compute/docs/autoscaler/scaling-cpu-load-balancing>. This approach amounts to creating your own App Engine service. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
