ApsaraDB for Memcache:Features

Last Updated:May 19, 2022

Distributed architecture, freeing businesses from the impact of single point of failure (SPOF)

  • ApsaraDB for Memcache uses a distributed cluster architecture. Each node is composed of two servers for hot backup and is capable of automatic disaster tolerance and failover.

  • Multiple types are available to cope with different business stresses with unlimited database performance expansion.

  • ApsaraDB for Memcache supports data persistence and backup recovery policies. It effectively secures data reliability and avoids the impact to the backend databases when the cache becomes invalid because of the physical node faults.

A multi-level security defense system to resist more than 90% of network attacks for you

  • DDoS defense: Real-time monitoring of network access is enabled. The source IP address gets cleaned in the event of high-traffic attacks. If the cleaning turns out ineffective, the traffic gets redirected to a black hole.

  • IP address whitelist configuration: A maximum of 100 server IP addresses can be configured in the whitelist for accessing an instance, directly putting risks under control from the source.

  • VPC virtual network: ApsaraDB for Memcache is fully connected to VPC and you can build an isolated network environment based on Alibaba Cloud.

  • SASL(Simple Authentication and Security Layer) authentication: SASL-enabled user identify authentication to safeguard data access security.

Improved tools to share your O&M workload for cache and databases

  • Monitoring and warning: Real-time monitoring and warning on instance information such as CPU utilization, IOPS, connections, and disk space is provided to view the status of the instance as needed.

  • Data management: Visualized data management tools are available for you to easily handle data operations.

  • Source code and distributed maintenance: Professional database kernel experts offer maintenance services to save your effort on maintaining Memcache source code and distributed algorithms.
