What each one is

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

etcd

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

Redis

A versatile in-memory database engine that enables sub-millisecond data access and processing for caching, stream processing, session storage, search, and machine learning workloads. Available as both open-source software and managed cloud services across multiple cloud providers.
