Product Advantages

Deliver faster experiences with an in-memory database that enables sub-millisecond performance

High Availability

Maintain a high uptime, with automatic failover on the master/standby or cluster instance types. The standby node takes over within a few seconds ensuring higher availability and reliability than single-node instances.

On-demand Scalability

Scale instances up and down with no service downtime (on master/standby or cluster instances), or with minimal interruption within minutes (on single-node instances).

Enabling Real-time Gamification

Live leaderboards (scores, ranks, analytics) present huge challenges for developers, with the need to scale up to thousands or even millions of users in real-time.

Advantages

Fast Data Access

Instantly retrieve frequently accessed data from an in-memory data cache instead of relying entirely on slow disk-based databases.
Easy Scalability

With just a few clicks, resize your DCS instances to manage spikes in load and traffic.
Backup and Restoration

Back up data to OBS and restore it with just a few clicks.

Powering Huge Websites and Apps

DCS for Redis is ideal for websites, web apps, and social networking apps. The Redis Set data structure can maintain session data, while the Redis String data structure can maintain static cache files.

Advantages

Handle Massive Traffic

DCS for Redis can help enable sites to handle millions of visitors, by caching pages and delivering them instantly.
Pay-per-Use

Get the DCS instances you need and only pay for what you actually use.

Claims-processing & Fraud-prevention Platforms

DCS for Redis delivers high concurrency to keep up with instant transactions, security, and data reliability for financial apps.

Advantages

High Availability

HA architecture ensures that faults in a single cache node do not affect services.
Security

Security measures include requiring credentials (username and password) and providing audit logs.
Backup and Restoration

Data can be backed up to OBS and restored with just a few clicks.

Single-node

Single-node

Each single-node DCS instance runs on only one cache node and provides 128 MB to 64 GB in memory capacity. Recommended only when non-critical caching is needed.

Data Persistence

Data Persistence

By default, data persistence is enabled for both master/standby and cluster DCS instances. Data is flushed to disks with second-level latency.

Data Migration

Data Migration

DCS for Redis provides two migration modes: importing data from files (by uploading the file to an OBS bucket in the same region as the DCS instance) or migrating data online.

Data Backup and Restore

Data Backup and Restore

Initiate a manual backup at any time, or schedule automatic data back-ups. Each piece of data has three replicas. If an error occurs, or data becomes corrupted, you can restore your data from a backup with just a few clicks.

Network Isolation

Network Isolation

Tenants in different VPCs or security groups cannot connect to each other or access each other's resources, keeping assets separated and compartmentalized if necessary.
