What each one is

The product in its own terms, so the numbers below have context.

Memcached

A free, in-memory key-value cache designed to reduce database load and improve application performance by storing temporary copies of frequently accessed data from databases, APIs, or rendered pages. It distributes cache across multiple servers in a cluster, with each piece of data stored in a single consistent location for reliable retrieval.
