Concepts & Architecture

A Redis Enterprise cluster is composed of identical nodes that are deployed within a data center or stretched across local availability zones. Redis Enterprise architecture is made up of a management path (depicted in the blue layer in Figure 1 below) and data access path (depicted in the red layer in Figure 1 below).

  • Management path includes the cluster manager, proxy and secure REST API/UI for programmatic administration. In short, cluster manager is responsible for orchestrating the cluster, placement of database shards as well as detecting and mitigating failures. Proxy helps scale connection management.
  • Data Access path is composed of master and slave Redis shards. Clients perform data operations on the master shard. Master shards maintain slave shards using the in-memory replication for protection against failures that may render master shard inaccessible.
