Web Sockets versus TCP Sockets

The Azure Web PubSub Service can be used for real-time messaging applications using web sockets and the publish-subscribe pattern. We use subprotocol json.webpubsub.azure.v1 to exchange messages in JSON format. The actual xml message is a passed as a string via the data node.

PaaS vNext

PaaS vNext means you can deploy Azure Web Apps, Functions, Logic Apps, API Management and EventGrid to an Arc-enabled Kubernetes cluster, so not as a PaaS offering in the public cloud. Arc-enabled means that you can run the cluster anywhere: in an Azure VM, in the Amazon cloud, on the Google cloud platform or on premises. All in your own private compute space.
