 [DrupalDevDays 2024 Bulgaria](https://ddd2024.drupalcamp.bg/)[Slides](https://ddd2024.drupalcamp.bg/sites/default/files/slides/devdays-burgas-2024-caches.pdf) 

 

 

 

High-level introduction to caches in Drupal, contextualizing and correlating the diverse caching systems that may come into play in a Drupal site, with the aim of providing a comprehensive and understandable overview of this topic.

Previous knowledge is not required, as we will start from the very basics, providing a definition of cache and some basic concepts, to gradually move on to more complex topics.

*Index*:

- General introduction
- PHP: OPcache
- Drupal core (Cache Backend, Cache Services, Cache API, Dynamic Page Cache, Internal Page Cache).
- In memory caching (Memcached)
- Cache proxy (Varnish)
- CDN.
