Plan a Redis Flex deployment on Kubernetes

Review the hardware requirements, sizing guidelines, and known limitations before you deploy Redis Flex.

Version requirements

Redis Flex requires:

Get started with Flex on Kubernetes

Mon, 01 Jan 0001 00:00:00 +0000

Note:

This page applies to Redis database version 7.4 and earlier using Auto Tiering. If you use version 8.0 or later, see Redis Flex.

Flex extends your database capacity by combining RAM and flash (SSD) storage. This tiered architecture keeps frequently accessed (hot) data in RAM for sub-millisecond latency while storing less active (warm) data on flash to reduce costs and increase capacity.

Prerequisites

Redis Enterprise Software for Kubernetes supports using Auto Tiering (previously known as Redis on Flash), which extends your node memory to use both RAM and flash storage. SSDs (solid state drives) can store infrequently used (warm) values while your keys and frequently used (hot) values are still stored in RAM. This improves performance and lowers costs for large datasets.
