Re: [lwip-users] Tunnel solution for HTTP server expose to Internet

[Sergio R. Caprile]

Summing up:
Yes, you can avoid writing apps, but you have to host a web page
somewhere. Either a CGI on the server or a javascript on the browser
will connect to the database (or the broker if you just need realtime
and no history, that is: no persistence)

No, some of these services are free for low traffic volumes. Heroku is.
Eclipse runs a free MQTT broker (but it does not provide persistence, if
you need it). I don't know of any free hosting with db, btw.

And yes, you have to think about privacy. (good) Cloud services can
provide certificate based data reading, with Heroku you write your app,
with hosting a server+database, well, you manage db passwords and user
accounts.
