WordPress Cluster on MassiveGRID PaaS
The WordPress Cluster Kit v2 deploys a highly available, horizontally scalable WordPress topology on MassiveGRID PaaS: a load balancer in front of several application servers, a replicated MariaDB cluster, Redis caching and shared file storage. It is the package for WordPress sites that cannot afford downtime or a traffic ceiling.
Both buttons open the MassiveGRID PaaS dashboard with WordPress Cluster pre-selected. The trial needs no credit card.

What is WordPress Cluster?
A standalone WordPress server has two hard limits: one machine can only serve so many requests, and if that machine fails the site is down. The Cluster Kit removes both. Requests arrive at a load balancer and are spread across two or more PHP application servers; the database runs as a replicated MariaDB cluster; uploads and plugin files are kept in sync across servers; and Redis holds object-cache data so repeated queries never hit the database.
Version 2 of the kit adds a guided installer that picks sensible servers for your expected traffic, lets you choose between MariaDB Galera (multi-primary) and primary-secondary replication, and switches on horizontal auto-scaling so extra application servers are added and removed on load triggers. The whole topology is described in a JPS manifest that you can inspect, export and re-use.
What the WordPress Cluster Package Deploys
Marketplace packages are not bare container images. One click provisions a complete, production-shaped environment on MassiveGRID infrastructure.
- Load balancer: LiteSpeed ADC or NGINX, terminating SSL and distributing requests across the application layer with health checks and session persistence.
- Application servers: Two or more LiteSpeed or NGINX PHP nodes, all serving the same WordPress code, scaled horizontally on CPU and memory triggers.
- MariaDB cluster: Galera multi-primary or primary-secondary replication, so a database node can fail without losing writes or taking the site offline.
- Redis cache: An object-cache layer shared by every application server, cutting database queries and response times for logged-in users and WooCommerce carts.
- Shared storage: Uploads, themes and plugins live on a shared volume so every application server sees the same files immediately.
Why Teams Choose WordPress Cluster
No single point of failure
Every layer runs on at least two nodes. Combined with MassiveGRID's redundant infrastructure and 100% uptime SLA, the site stays up through hardware and software faults.
Horizontal auto-scaling
Application servers are added when load rises and removed when it falls, so you pay for cluster capacity only while you need it.
Optimised for WooCommerce
Redis-backed sessions, replicated MariaDB and sticky load balancing keep carts and checkouts consistent across servers, which is where naive WordPress clusters break.
Guided installer
The kit asks about expected traffic and picks server types, database mode and scaling limits for you. Every choice can be changed later from the dashboard.

Who Runs WordPress Cluster on PaaS
High-traffic publishers
News, media and content sites where a front-page story can multiply traffic tenfold within minutes.

Enterprise and government sites
Organisations with uptime requirements written into contracts, running in a region of their choice with data replicated inside it.
Why Run WordPress Cluster on MassiveGRID PaaS
Built for uptime. WordPress Cluster runs on MassiveGRID's high-availability platform, where every environment is covered by a 100% uptime SLA. Nodes live on redundant hosts, storage is replicated, and failed containers are restarted or migrated automatically.
Pay for what you use. Billing is hourly and per cloudlet (128 MiB RAM plus 400 MHz CPU). Vertical auto-scaling adds and removes cloudlets as load changes, so a quiet WordPress Cluster environment costs a few dollars a month and a busy one grows without a migration. Full details are on the PaaS page.
Your choice of jurisdiction. Deploy in New York, London, Frankfurt or Singapore and keep data inside the region your users or regulators require. MassiveGRID is ISO 9001 certified and GDPR compliant, and has run hosting infrastructure since 2003.
No lock-in. The package is a standard Jelastic Packaging Standard (JPS) manifest. You keep root-level access to the containers, can export the manifest, and can move the workload to any other Jelastic-compatible platform or to your own servers at any time.
