Kubernetes is becoming an industry standard for orchestrating containerized applications efficiently and at scale. Redis Labs has developed support for a robust, highly available K8s deployment simplifying lifecycle management of multiple Redis Enterprise databases on a Redis Enterprise Cluster. Redis Labs K8s deployments are supports over multiple K8s distributions and implementations.

    Redis Labs Kubernetes Architecture – Overview

    Redis Labs bases its Kubernetes architecture on the several vital concepts. Layered architecture Kubernetes is an excellent orchestration tool, but it was not designed to deal with all the nuances associated with operating Redis Enterprise. Therefore, it can fail to react accurately to internal Redis Enterprise edge cases or failure conditions. Also, Kubernetes orchestration runs outside the Redis Cluster deployment and may fail to trigger failover events, for example, in split network scenarios.

    Redis Enterprise K8s Operator-based deployments – Overview

    The Redis Enterprise Operator is the fastest, most efficient way to deploy and maintain a Redis Enterprise Cluster in Kubernetes. What is an Operator? An Operator is a Kubernetes custom controller which extends the native K8s API. Operators were developed to handle sophisticated, stateful applications that the default K8s controllers aren’t able to handle. While stock Kubernetes controllers—for example, StatefulSets—are ideal for deploying, maintaining and scaling simple stateless applications, they are not equipped to handle access to stateful resources, upgrade, resize and backup of more elaborate, clustered applications such as databases.
