# Introduction

Recently, I had to implement a cache in an application to avoid unnecessary database queries. Having worked with Redis in the past, I realized that implementing a cache with Redis can be quite straightforward and effective when done correctly.

# Redis vs Memcached

Redis is almost like a NoSQL database but excels as a cache due to its key-value storage model. The choice between Redis and Memcached depends on the use case and data volume. If you need to store session information, Memcached is a good choice. However, for extensive queries involving larger data sets, Redis is more suitable. Memcached uses the application’s memory to store data, while Redis is a distributed cache, independent of the application’s memory, allowing it to scale vertically as demand grows.
