Many users ask us if WebSocket is supported on Clever Cloud. Of course it is! WebSocket works like a charm with PlayFramework 2 and Node.js apps deployed on Clever Cloud.

You can check a small demo we have uploaded right here:
nodejs-demo.cleverapps.io (be sure to have a mate visiting this link at the same time)

If you want to try some experiments on Clever Cloud, here are some ressources with WebSocket use cases:

socket.io: A powerful JS framework to enable WebSocket in your projects.
Real-time Paint-like with Play: A great tutorial to check Play’s real time abilities.
Learn real time with node.js If you’re new to node.js, CodeSchool may help you.

Have fun 😉

K3s and K8s (upstream Kubernetes) address different needs, even though both share the same CNCF-certified foundation.
