Is an on-premise server mandatory for a self-hosted chat app?

The answer is No. The on-premise chat server is not mandatory for a self-hosted chat app. While it was the norm, you can now deploy on-cloud based on your requirements. However, the choice depends on the specific needs. Deploying on the cloud server requires developer support for scalability. The on-premise server offers complete access to scale.
