Why Huawei Cloud DCS?

Cost-Efficient: Higher Performance at Lower Cost

Cost-Efficient: Higher Performance at Lower Cost

  • 100,000/400,000 QPS on a single shard for the basic/professional edition

  • Data persistence, backup, and restoration

  • 30% lower costs with in-house developed Arm-based architecture. x86 is also supported.

Flexible: Instances Provisioned in Seconds with a Wide Range of Memory Options

Flexible: Instances Provisioned in Seconds with a Wide Range of Memory Options

  • Instances come in single-node, master/standby, Proxy Cluster, Redis® Cluster, and read/write splitting types.

  • Memory options range from 128 MB to 1,024 GB to meet different needs.

  • Create DCS instances with just a few console clicks without having to prepare servers.

Monitoring: 40+ Metrics, Custom Thresholds, Alarm Policies

Monitoring: 40+ Metrics, Custom Thresholds, Alarm Policies

  • External metrics include the number of commands, concurrent operations, connections, clients, and denied connections.

  • Resource usage metrics include CPU usage, physical memory usage, and network input or output throughput.

  • Redis® kernel monitoring and statistics, custom monitoring threshold and alarms are also supported.

Stable: High Availability, Failover in Seconds

Stable: High Availability, Failover in Seconds

  • Each shard in a cluster instance is deployed in master/replica mode. A replica is automatically promoted to master when the master is faulty.

  • Automatic failover to the standby node does not change the instance IP address.

Secure: Authentication, VPC, Subnet

Secure: Authentication, VPC, Subnet

  • VPC- and subnet-level tenant isolation and traffic filtering

  • Strong password protection, and password change/reset

  • Interworking with Cloud Trace Service (CTS) to record and audit tenant management operations
