We have certain data which is considered as configuration data and mostly act as lookup data such as List containing name of Countries, Cities and other data relevant to the project. We have 3 farms deployed in Americas, Europe and Asia Pacific region.
Challenge is we have to share data between these 3 farms, One of the options which we have done create a special subsite within global site collection called as "Administration" subsite and dump all list in this subsite.
Which means each farm has its own administration subsite and thus causing data redundancy. Goal is to have these configuration list data at one location say a Farm in Europe all three farm share this data.
Challenges are it will cause performance issue.
Question here is, does any one know if there are any best practices or microsoft recommendation when it comes to sharing of data across farm which are divided apart physically. i.e. Store data centrally Vs Local data storage and have redundancy.
