I have clustered Magento in Google Cloud, and i have 2 frontend webservers, 1 admin + nfs server (here it goes mystore/admin session) and 1 database.
Since files on frontend webserver are delivered from nfs to then via nfs share (only
/media) and lsyncd for rest of files, i was wondering if anyway admin people works only on
/admin dedicated VM, frontend webserver only needs to read Magento files, correct?
Session and cache is inside Redis dedicated instaces on database VM
If answer is yes (and i asking this question here becouse i think is more a developer/magento question rather then ServerFault) i could just mount the NFS (
/admin vm) vm harddisk where Magento is located in Read only mode directly to webservers.
