How can Host this site to cloud?

Dear Sir,

I am able to show my PLC parameter on web by using your code.
But How can I deploy this web app to cloud...?

Because my PLC is in local network so even I deploy to cloud but from cloud how can I access my PLC by using "opcda://192.168.0.5/Graybox.Simulator.1"

because link "opcda://192.168.0.5/Graybox.Simulator.1" only accessible in local network..
Are you think any solution ?

Thanks,
