Tair（Redis OSS-compatible） supports the standard, cluster, and read/write splitting architectures. You can select an architecture that suits your business requirements.

Architectures

The following table describes the supported instance architectures. You can click the link to an instance architecture to view details about the architecture.

Instance architecture	Architecture diagram	Scenario
Standard master-replica architecture The master-replica architecture is used to ensure high availability.		Support for more native Redis features. Persistent storage on Redis instances. Stable query rate on a single Redis instance. Use of simple Redis commands, where only a few sorting and computing commands are required.
Cluster master-replica architecture In the cluster architecture, each data shard runs in master-replica mode.		Large data volume. High queries per second (QPS). Throughput-intensive workloads.
Read/write splitting architecture The read/write splitting architecture consists of the master and replica nodes and multiple proxy nodes.		High QPS. Support for more native Redis features. Persistent storage on Redis instances.
