Facades provide a simpler way to use these services, similar to how you would use static methods on a class, but behind the scenes, they dynamically resolve instances from the service container. This allows you to work with complex components in a more intuitive and elegant manner.

For example, consider the Cache facade in Laravel:

use Illuminate\Support\Facades\Cache;

$value = Cache::get('key');

Laravel provides several built-in facades for common tasks, like Cache, Config, Session, Route, DB, Log, and more. Additionally, you can also create your own custom facades to provide an easier-to-use interface to your application's custom services.

2nd example:-

namespace App\Facades;

use Illuminate\Support\Facades\Facade;

class MyCustomServiceFacade extends Facade
{
    protected static function getFacadeAccessor()
    {
        return 'my-custom-service'; // The service identifier in the container
    }
}

By using facades, you can access various parts of the Laravel framework and your application’s services in a convenient and consistent manner. They are a fundamental concept in Laravel that contribute to the framework’s ease of use and developer experience.
