I am trying to set nginx load balance I have planned like Load Balance Nginx + Two Magento Instance + one database, after some search around that topics I have some doubts.
As per this answer, it is stated like
You can end up with big issues because of different extensions or when saving different config values
As per this blog, the approach was each magento instance have separate database. But I feel it seems to hard sync files and db in all three instance.
Please suggest how to achieve nginx load balance without degrade performance.
