Gaming
Memcached provides fast access to leaderboards.
Advantages
Fast Data Access
Retrieve frequently used data (such as leaderboards) from an in-memory data cache instead of relying entirely on slower disk-based databases.
Scalability
With just a few clicks, resize your DCS instances online to accommodate application load spikes.
Backup and Restoration
Back up data to OBS and restore it in just a few clicks.
E-Commerce
DCS for Memcached provides fast concurrent access to frequently requested data, such as best sellers and daily deals, and is scaled easily as load increases.
Advantages
High Concurrency
DCS for Memcached supports up to 100,000 queries per second.
Easy Scalability
With just a few clicks, your DCS instances can be resized online to accommodate application load spikes.
Data Persistence
Data is automatically persisted to disks, maintaining data durability and security.
Internet
DCS for Memcached is ideal for social and web apps. The Memcached Set data structure can maintain data about relationships between friends and the String data structure can cache static files.
Advantages
High Concurrency
DCS for Memcached supports up to 100,000 queries per second.
Pay-per-Use
You can buy DCS instances as needed, and only pay for the instances you actually use.
Easy Scalability
With just a few clicks, your DCS instances can be resized online to accommodate application load spikes.
Finance
DCS for Memcached delivers high concurrency, 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 security credentials (username and password) and audit logs.
Backup and Restoration
Data can be backed up to OBS and restored with just a few clicks.
Functions
-
High Availability
If a master cache node becomes faulty, the standby cache node will take over within seconds.
-
Flexible Specs
You can choose between single-node and master/standby instances from 2 GB to 64 GB.
-
Scalability
DCS instances can scale online and hitlessly as the instance load increases.
Failover
DCS clients will not perceive the failover because the instance IP address exposed to them remains unchanged.
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.
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.
-
Security
Security measures include user identity authentication, VPCs, subnets, security groups, and audit logs.
-
Metric Monitoring
You can view over 30 metrics and customize alarm thresholds and policies.
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.
Network isolation
Tenants in different VPCs or security groups cannot access each other or use each other's resources.
Traceability
DCS for Memcached works with Cloud Trace Service to record and audit tenant management operations.
User authorization
DCS for Memcached checks password complexity and protects against password cracking. Users are required to change or reset DCS instance passwords periodically.
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 that will receive an alarm if that threshold is crossed. When the number of keyspace misses reaches 30, the user will receive an alarm.
