What each one is

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

etcd

Leader

etcd is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines. It gracefully handles leader elections during network partitions and can tolerate machine failure.

Independently observed

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.
