Hi We are building an application which delivers currency exchange rates to customers over the web.
The exchange rates come from an existing .net WCF Duplex service. And the rates are streamed for a period of 60 seconds over a tcp connection. i.e. constantly changing data (one or two updates per second), not a single request/response. Also, different pricing is applied depending on who the customer is, so it is not a single source of data. It is different for each customer. And so a new instance of the data stream is created for each incoming request. We are building a new API which would sit in front of the existing WCF service (and behind the website backend) and we are considering using Zero mq to distribute the rates. So it is server-to-server comms. (**Not** the browser to server part) I am trying to identify if I should use a stream socket http://hintjens.com/blog:42 Or if a simple REQ/REP pair would be fine. Or if there is some other pattern that is more appropriate. Some things I'm struggling with: Given the data is different for each request I presume I cant have a single RES server. I'd need to new one up for each incoming request? How would that work? Also, how would you then co-ordinate the correct data is returned to the correct client? Could the zeroMQ part be hosted inside an existing .net Web.api ? thanks for any advice ------------------------------ This message may contain confidential or privileged information.
