Scalable WordPress Cluster in a Single Click

here we are discussing some interesting topic

  • For distributing incoming traffic within a cluster, a WordPress NGINX load balancer is used; herewith, it can be manually scaled horizontally after installation, whilst the newly added node(s) discover available application servers automatically
  • The WordPress application itself is handled with two NGINX PHP servers that are automatically scaled based on the pre-configured triggers
  • Two replicated MySQL DB servers to store and operate user data
  • Dedicated Data Storage node to eliminate data duplication and ensure the same content presence across all application servers
