In our company we have already 1 tomacat appserver(SER1) and 1 CMS database(DB1). We have planned to have another app and CMS database in new servers(SER2 and DB2). Ser1 and DB1 will be down after some month.
Here is what I required
Ser1 -> DB1
Ser2 -> DB2
DB1 and DB2 data need to sync.
Both these servers will be pointing to same File repo server which is in share drive.
What is the best approach? do I need to create clustering?
