We are an IT outsourcing company with a wide variety of customers and services. We specialize in running applications for SaaS application vendors in addition to standard services like Hosted Exchange.
Customer A is a vendor of a SaaS business application suite with well over 10 000 users and applications covering most business needs. They now wish to move/migrate their current and future customers to Hosted Exchange. There are though some requirements that needs to be met in this case. We need to set up a synchronization engine that can synchronize data between the two systems. In addition we need to bring in new functionality to enable data flow to and from other systems and protocols, out of the box, i.e. SyncML, ActiveSync, Google, Plaxo and so on.
Can anybody give us any advice on what product to use for the sync engine?
