I am looking to get some information on possible high availability solution using Kentico CMS. The example architecture is 4 web servers, with two database servers ( both servers have 2 kentico database installed). My question is how have people been able to get the data to replicate across the database (user accounts, comments, forums posts). In contacting kentico support they have mention 3rd party replication tools. Is that require? Has there been any success using 2008 replication.

Thanks,
James
