Laravel applications that hit the database on every request pay a performance tax that compounds fast. Redis caching eliminates redundant queries, cuts server costs, and delivers sub-100ms responses even under high-traffic loads.
**Why Redis — not file or database cache**
File cache adds disk I/O. Database cache queries the same engine you are trying to offload. Redis operates entirely in memory — reads complete in under 1 millisecond, and data survives application restarts via optional persistence.
For a mid-size e-commerce store processing 5,000 daily sessions, switching the cache driver from `database` to `redis` in Laravel's `config/cache.php` reduces MySQL queries per page view by 60–80%.
**Setting up Redis in Laravel**
Install the Predis client or use the phpredis extension — both are supported in Laravel 10 and 11:
```bash
composer require predis/predis
```
Update `.env`:
```
CACHE_DRIVER=redis
REDIS_HOST=127.0.0.1
REDIS_PORT=6379
```
**Cache frequently read data**
Product catalogs, category trees, and homepage widgets are prime candidates. Cache them once, invalidate on update:
```php
$products = Cache::remember('products.featured', now()->addHours(2), function () {
return Product::with('category')->where('featured', true)->get();
});
```
**Session and queue on Redis too**
Set `SESSION_DRIVER=redis` and `QUEUE_CONNECTION=redis` to move session storage and job queues into the same in-memory layer. This reduces database connections by 40% on a typical Laravel application.
**Real-world impact**
A Laravel-powered B2B catalog we built for a Kyiv distributor cut page load from 1.8 seconds to under 400ms after Redis integration — without changing a single database schema.
**When Redis is not enough**
For content that changes per user, combine Redis with Laravel's `Cache::tags()` — available with Redis and Memcached drivers — to invalidate precise subsets without flushing the entire cache.
