Magento uses the following caching terminology:
- Frontend: Similar to an interface or gateway to cache storage, implemented by Magento\Framework\Cache\Frontend.
- Cache types: Can be one of the types provided with Magento or you can create your own.
- Backend: Specifies details about cache storage, implemented by Magento\Framework\Cache\Backend
Two-level backend: Stores cache records in two backends—a faster one and a slower one.

<magento_root>/app/etc/di.xml(the Magento application’s global dependency injection configuration)
- Configuring your own custom cache frontend, which means you modify only
<magento_root>/app/etc/env.phpbecause it overrides the equivalent configuration in
Varnish requires no changes to the Magento configuration. For more information, see Configure and use Varnish.
