Web Services - WSDL Push API

Any help much appreciated. I am looking for suggestions for an architecture for the following scenario.

I am looking to setup a server/database to store a high frequency 开发者_如何学运维data set. The source data provider has made the following requirements for a destination system to be able to subscribe to the Push service.

• Must have a valid "HTTPS" URL.
• Web Services enabled to handle WSDL form data.
• SSL enabled

I am working from a blank slate, and I am looking for suggestions for best language/server/datastore combination.

Many thanks

PJ
