The Microsoft Patterns & Practices team has just published the third volume in a series on Windows Azure.
This guide focuses on the common challenges encountered when building, deploying and operating applications that run partly in the cloud and partly on-premises.
Of particular interests to me is the 2nd Chapter where data synchronization options are discussed. Likewise, there’s an appendix entry dedicated solely on data synchronization.
This is probably the best documentation/guidance available as of now on SQL Azure Data Sync Service.
I took the liberty of putting up the links that goes directly to the synchronization topics below.
I would suggest you download the entire guide though.
