Redis PHP 7.0+
An in-memory key-value data store used in PHP applications for caching, session storage, queues, rate limiting, and pub/sub — providing sub-millisecond data access compared to database queries.

Cache Warming Strategies PHP 5.0+
Pre-populating a cache before traffic arrives — preventing the cold-start thundering herd where every request misses a cold cache simultaneously after a deploy.
