options for building a realtime website

I'm going to build an webbased application which is controlling and monitoring tons of realtime data. think about few thousand valves pipes pumps and sensors.

Please list a technology stack you would use to build a realtime website with an educated guess about performance. The environment is 'ideal' all openstandards are available. so no IE6 etc backward compatibility is needed. Current and future proof technologies pl开发者_如何学Pythonease.

server side: database web-server - which one / combination makes it easy to support real-time pushing of data?

client side: what kind of client environment (javascript Libraries) support showing and updating tons of realtime data?

You can have a look at Goliath

I recommend you have a look into Socket.IO which works best with Node.JS and might be the best fit for handling many long lasting concurrent real time connections. I would say that the choice of the database depends more on where your real time data is coming from and how it is supposed to get in the database.

Me too. So I'm writing a frame work that can do that. It's based on lighttpd front end, and multiple fcgi backend servers. The original Android was also tested with another framework that is based on it. It's open source so you might want to use it as a starting point.

I haven't been able to write a realtime app, but I've dabbled a bit with http://socket.io/ and node.js, and it's a joy to get started with.

App engine has a js channel api which seems nice. You should take a look to see if hosting on app engine is a option.

If you're dealing with "real time" stuff server-side, I recommend clojure for managing concurrent state.
