How to Install Redis with Docker

Redis is an in-memory key-value data store used as a cache, a job queue and a session manager. With Docker you bring it up from a single docker-compose.yml file, with persistence on a volume, a mandatory password and a healthcheck. This guide covers the installation, how to secure it and how it differs from Valkey.

Microsoft Garnet: a high-performance cache alternative

Garnet es el servidor de caché abierto por Microsoft Research que habla el protocolo de Redis pero está escrito en .NET 8 con un núcleo de almacenamiento orientado a hardware moderno. Tras casi dos años en público, muestra números interesantes y una arquitectura que merece mirarse con calma, aunque el ecosistema Redis siga siendo más maduro.

Dragonfly: the modern cache inspired by Redis

Dragonfly lleva tres años como alternativa compatible con Redis, pero con arquitectura multihilo y sin fork para persistencia. En 2025 ya no es una curiosidad: hay despliegues serios que lo eligen por coste y latencia. Repaso de qué cambia y cuándo compensa mirarlo con calma.

Valkey: The Open Fork After Redis’s License Change

Redis moved to dual SSPL/RSAL licensing in March 2024, no longer meeting the OSI open-source definition. Valkey emerged as a BSD 3-Clause fork backed by AWS, Google Cloud, Oracle, and the Linux Foundation, fully protocol-compatible with Redis 7.2. Migrating is almost always trivial: swap the binary or the Docker image.

Redis: Caching Strategies Every Backend Should Know

Redis alone isn't a caching strategy, just an ingredient: picking the right pattern among cache-aside, read-through, write-through, and write-behind, sizing TTL to how fast data actually changes, invalidating explicitly for critical data, and mitigating thundering herd with jitter and locking are the decisions that actually matter in production.
