[opencms-dev] OpenCMS 8.5.2 in Cluster

[Georgi Naplatanov]

Hi

I think that running OpenCms in a cluster won't be a problem if:

  - you use 1 db server or all db servers use synchronous replication
  - some parts of application folder are shared between all OpenCms 
instances (Samba or NFS), like /export/ folder
  - network enabled FlexCache cache implementation, like Ehcache.

As Achim mentioned in this list, OCEE module is not expensive (at least 
for western Europe standard), so you may decide to do something else.

Best regards
Georgi
