Using websocket in Banking?

Question

Node.js and Tornado are excellent servers that can be both websockets and http servers, but, how about using them in Banking applications?

Of course, not for 24h, but they will be used for the time a bank will be opened, for example, for 8 hours.

Is that a good idea, or keeping the connection opened for 8 hours is so much?

Answer 1

So long as you don't have network issues then keeping a websocket open for 8 hours isn't a problem.

You could also setup your code to reopen the websocket in the background if it dies.
