Storage-optimized instances apply to latency-insensitive scenarios that require high concurrency, ultra-large-scale data storage, and ultra-low costs. View details >

Various Architectures: Single Shard, Master-Replica, Read/Write Splitting, and Distributed Cluster

Single node instances are suitable for caching scenarios. Master-replica instances feature automatic failover. Read/write splitting instances apply to scenarios where more reads are processed than writes. Cluster instances can be scaled out.

Master-Replica Architecture

The replica node synchronizes to the master node in real-time. If the master node fails, the system automatically performs a failover and restores the services within a few seconds. Then, the replica node takes over the workloads. Your service is not interrupted during the failover process. The master-replica architecture ensures the high availability of your services.

Cluster Architecture

Cluster instances run in a distributed architecture. Each shard contains a master node and a replica node to ensure high availability. Failovers are triggered when the master node fails. Multiple specifications are provided to deal with different workloads. You can upgrade your instances to improve the performance of the database service.

Read/Write Splitting Architecture

The read/write splitting architecture applies to scenarios where more reads are processed than writes. Each read/write splitting instance supports a maximum of 100,000 writes per second and 600,000 reads per second. This helps you eliminate the performance bottleneck of reading and writing hotkeys.

Data Security: Backup and Restoration, Multi-Layer Network Protection, and Disaster Recovery

Supports automatic backup, quick restoration, multi-layer network protection, zone-disaster recovery, and geo-disaster recovery

Backup and Restoration

Automatically performs backups and supports disaster recovery. You can restore data that is accidentally deleted to minimize your business losses.

Multi-Layer Network Protection

Virtual Private Cloud (VPC) isolates data transmission at the transport layer. Anti-DDoS detects and mitigates volumetric DDoS attacks in real-time. It allows you to configure more than 1,000 IP address whitelists to block malicious IP addresses.

Disaster Recovery

Supports zone-disaster recovery, geo-disaster recovery, and cross-region disaster recovery to avoid data corruption at the physical layer.

In-Depth Kernel Optimization

Alibaba Cloud Technical Experts have optimized the kernel of open-source Redis® to prevent out-of-memory errors and patch vulnerabilities.

Elasticity: Multidimensional Scaling and Transparent Upgrades

Dynamic upgrades to improve the performance and capacity of your instances. You can also switch between different architectures without service interruption.

Data Capacity Expansion

Tair (Redis® OSS-Compatible) instances are available in different memory capacities. You can adjust the memory capacity of your instance to meet business requirements.

Performance Upgrading

The cluster architecture allows you to scale the storage and throughput of the databases. This eliminates the performance bottleneck and can handle tens of millions of reads and writes per second.

Multiple Architectures

Supports the single node caching architecture and master-replica architecture to meet different business requirements. You can upgrade to master-replica instances or downgrade to standard instances when necessary.

Intelligent O&M: Professional Monitoring and Data Management Platform, and Automatic Kernel Version Upgrading

The Data Management (DMS) console and the Tair (Redis® OSS-Compatible) console are easy to use and can reduce management and maintenance expenses. The system is automatically upgraded to the latest version.

Monitoring Platform

Monitors the CPU utilization, number of connections, and disk usage of instances in real time and raises alerts. This allows you to gain insights into your instances.

Visualized Management Platform

You can perform common and high-risk operations with only a few clicks in the Tair (Redis® OSS-Compatible) console. For example, you can clone instances, back up data, or restore data.

Visualized Data Management Platform
