Diagram illustrates how clustering of eZ Publish Platform is typically setup, the parts illustrates the different roles needed for a successful cluster setup. Number of web server, memcached servers, Solr server, Varnish servers, Database Severs, NFS servers and if some servers takes care about several roles (typically running memcached across the web server) does not matter is up to you and your performance needs. The minimal requirements are the following (with what is currently supported in parentheses): - Shared HTTP cache (using Varnish)
- Shared Persistence cache and Sessions (using Memcached)
- Shared Database (using MySQL/MariaDB)
- Shared Filesystem (using NFS)
For further details on requirements, see Requirements doc. While this is not a complete list, further recommendations includes: - Using a CDN for improved performance and faster ping time worldwide
- Using Solr for better search and better search performance

- In General: Make sure to use later versions of PHP and MySQL/MariaDB within what is supported for your eZ Publish Platform version to get more performance out of each server.
