CLoud Server TCP/IP
asked 8 hours ago by @qa-bht6md40ua2alueucbam 0 rep · 25 views
I am building a smart meter/DLMS application. The meter connects to a server using a public IP address and TCP port (for example, IP: x.x.x.x, Port: 4059).
I am looking for a free cloud service that provides:
A public/static IP address (or publicly reachable IP)
Ability to open and listen on custom TCP ports
Support for running a long-running Python or Node.js TCP socket server
24/7 connectivity so meters can initiate connections to the server
I have looked at Firebase, but as far as I understand it only supports HTTP/HTTPS-based services and does not allow applications to listen on arbitrary TCP ports.
What free cloud providers would be suitable for this use case? Has anyone successfully hosted a TCP socket server for IoT devices or smart meters on a free cloud platform?
