The technology that powers WordPress sites on Flywheel, and makes them fast and secure is multi-layered and complex. Hopefully we can shed a little light on the parts and pieces that make up the Flywheel server infrastructure.
|Caching Layer||The Flywheel caching is powered by the Varnish cache server. Varnish is an incredibly fast memory-based HTTP accelerator, that we’ve customized with rules specific to WordPress and our environment.|
|Web Server Layer||We use the Nginx web server to serve up static files, and act as a reverse proxy to the processes that run PHP. Nginx also handles all of the rewrite rules associated with serving up WordPress websites.|
|PHP Layer||We run chrooted PHP-FPM instances to execute the PHP code that runs the WordPress code. This PHP is optimized with things like APC.|
|Database Layer||MySQL powers the database. Pretty straightforward installation, with a performance tuned configuration.|
Of course these are just the major components that power a site on Flywheel. In addition to these there are myriad other services and processes that provide enhanced security, performance, manageability, and reliability. Together these systems comprise the Flywheel platform, which enables your sites to run incredibly fast and be incredibly secure.
