Cloudways for WordPress: setup, caching & speed
WordPress on Cloudways runs on a managed stack — PHP-FPM, Varnish, Redis or Memcached object caching, and Cloudways' own Breeze plugin — without needing root-level server administration.
The stack, in plain terms
- PHP-FPM handles PHP execution with process management tuned per app.
- Varnish serves a full-page cache for anonymous visitors, which is where most of the visible speed gain comes from on content-heavy sites.
- Redis or Memcached caches database queries and objects — matters most for WooCommerce and membership sites with logged-in, dynamic traffic that bypasses Varnish.
- Breeze is Cloudways' own free caching plugin that ties the above together at the WordPress admin level, plus browser caching and basic minification.
Staging before you touch production
Cloudways gives you one-click staging environments per app, so plugin updates, theme changes, or a PHP version bump can be tested on a clone before it touches the live site. This matters most for WooCommerce stores, where an untested update during business hours is expensive.
What actually moves Core Web Vitals
In our testing, the biggest single lever is enabling Varnish full-page cache correctly (it's not always on by default per-app) and pairing it with a CDN in front of static assets. Object caching (Redis) mainly helps Time to First Byte on dynamic, logged-in pages — it won't move a Lighthouse score for an anonymous visitor nearly as much as people expect. Image compression and deferred non-critical JS still matter regardless of host.
For a store specifically, see our upcoming WooCommerce setup guide (linked from the roadmap); for general speed checklist steps, treat Varnish + CDN + image optimization as the first three things to verify, in that order.
Common questions
Do I need a caching plugin if Cloudways already caches at the server level?
Breeze is still worth installing because it controls settings (like exclusion rules for cart/checkout pages on WooCommerce) that the server-level cache can't infer on its own. Server caching and Breeze work together, not as alternatives.
Can I migrate an existing WordPress site to Cloudways?
Yes, via Cloudways' own migrator plugin or a manual database/files transfer. Test on a staging app first rather than pointing DNS before you've verified the migrated site.
