WordPress Cluster Kit v2

The WordPress Cluster Kit v2 is an automated solution designed for large enterprises and mission-critical websites.
It offers high availability for all topology elements, with automatic scalability and redundant components.

📐 Cluster Architecture​

  • Application Servers: auto-scalable to handle load variations.
  • Load Balancers: LiteSpeed (with HTTP/3 and extra features) or NGINX in cluster.
  • Database: MariaDB Galera Cluster (multi-primary, synchronous) or primary-primary replication.
  • Storage: GlusterFS optimized with failover (optional) or shared NFS.
  • Security: WAF, brute force attack protection, and SSL with Let’s Encrypt (auto-renewable).

⚙️ Installation Options​

By clicking Install in the self-service panel, the PaaS dashboard will open the installation window, allowing customizations:

🔄 Scaling Strategy​

Defines the automatic horizontal scalability policy:

  • Low Load: adds 1 server if workload > 70%, removes 1 if < 20%.
  • Medium Load: adds 1 server if workload > 50%, removes 1 if < 20%.
  • High Load: adds 2 servers if workload > 30%, removes 1 if < 10%.

🌐 Load Balancer​

  • LiteSpeed Web Server (recommended for maximum performance):
    • HTTP/3, advanced caching.
    • Available extras:
      • WordPress Brute Force Protection.
      • Web Application Firewall (Comodo ModSecurity).
  • NGINX: alternative option if LiteSpeed is not enabled.

🗄️ Database​

  • MariaDB Galera Cluster:
    • Multi-primary.
    • Synchronous replication.
    • Fault resilience without manual failover.
  • Primary-primary replication: simplified deployment without Galera.

🔒 SSL​

  • Let’s Encrypt (Auto-Renewal): free, trusted certificate automatically renewed.
  • Internal SSL: valid only for the platform domain.

📦 Storage​

  • GlusterFS Cluster:
    • Distributed, parallel, and fault-tolerant.
    • Bidirectional synchronization and expansion without downtime.
  • Shared NFS: default option if GlusterFS is not selected.

🌍 WordPress Features​

  • Multisite Network: manage multiple sites from a single WordPress installation.
  • WooCommerce: complete and scalable online store.

🧩 Use Cases​

  • High-traffic corporate portals
  • Scalable e-commerce with WooCommerce
  • Multi-tenant agencies and SaaS (WordPress Multisite)
  • Critical environments requiring high availability and failover

✅ Benefits​

  • Guaranteed high availability
  • Automatic and configurable scalability
  • Resilient database (Galera)
  • Fast content delivery (HTTP/3 with LiteSpeed)
  • Fault-tolerant distributed storage (GlusterFS)
  • Integrated security (WAF + brute force protection)
