Usable Off the Shelf

Configure and launch cache servers within minutes in just a few clicks. Buy resources in on-demand mode and migrate services to the cloud platform without any change.

Easily Scalable

Quickly scale your DCS instances to the desired capacity in just a few clicks, and do it without interrupting services.

Secure and Reliable

HA architecture ensures that faults in a single cache node do not affect services. Username/password-specific access and audit logs keep your data secure and traceable.

Fully Managed

DCS for Memcached monitors your clusters based on custom alarm thresholds for over 30 metrics so that service abnormalities can be detected in a timely manner.

Functions

High Availability

If a master cache node becomes faulty, the standby cache node will take over within seconds.

  • Failover

    DCS clients will not perceive the failover because the instance IP address exposed to them remains unchanged.

Flexible Specs

You can choose between single-node and master/standby instances from 2 GB to 64 GB.

  • Single-node DCS instances

    Each DCS instance runs on only one cache node and provides storage capacity of 2 GB to 64 GB. These DCS instances are only recommended when caching is needed.

  • Master/standby DCS instances

    Each DCS instance provides storage capacity of 2 GB to 64 GB and runs on two cache nodes, one master and one standby. These DCS instances are recommended when high availability is needed.

Scalability

DCS instances can scale online and hitlessly as the instance load increases.

  • Online scaling

    With just a few clicks on the DCS for Memcached console, you can scale your instances to a desired capacity with no service downtime (master/standby instances) or with a minute-level interruption (single-node instances).

Data Reliability

DCS for Memcached supports data persistence, backup, and restoration.

  • Data persistence

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

  • Data backup

    You can initiate a manual backup at any time, or create policies to automatically back up data daily during off-peak hours. Each piece of data has three replicas. In the event of a misoperation or if data is corrupted, you can restore your data from a backup in just a few clicks.

Security

Security measures include user identity authentication, VPCs, subnets, security groups, and audit logs.

  • Network isolation

    Tenants in different VPCs or security groups cannot access each other or use each other's resources.

  • User authorization

    DCS for Memcached checks password complexity and protects against password cracking.
    DCS for Memcached requires users to change or reset DCS instance passwords periodically.

  • Traceability

    DCS for Memcached works with Cloud Trace Service to record and audit tenant management operations.

Metric Monitoring

You can view over 30 metrics and customize alarm thresholds and policies.

  • A wide range of metrics

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

  • Custom alarm thresholds and policies

    For example, if you suspect a service fault was caused by frequent keyspace misses, then you can set the keyspace miss threshold to 30 and specify the user who will receive an alarm if that threshold is crossed. When the number of keyspace misses reaches 30, the user will receive an alarm.
