Purchased Impact
Yes, you have purchased hybrid-storage instances. You can continue to use existing hybrid-storage instances.
No, but you plan to purchase hybrid-storage instances. You cannot select ApsaraDB for Redis hybrid-storage instances when you create ApsaraDB for Redis instances.

Recommendations for new instances

ApsaraDB for Redis Enhanced Edition (Tair) is a distributed NoSQL database service that features high availability and high performance. ApsaraDB for Redis Enhanced Edition (Tair) provides various series of instances based on storage media such as DRAM, NVM, and enhanced solid-state disks (ESSDs) to meet your requirements for low-latency access, persistence, and reduced overall costs. ApsaraDB for Redis Enhanced Edition (Tair) provides you with higher performance, more data structures, and more flexible storage methods. This helps you meet business requirements in different scenarios. For more information, see Overview.

  • Performance-enhanced instances: Performance-enhanced instances use the multi-threading model and provide about three times the performance of ApsaraDB for Redis Community Edition instances of the same specifications. Performance-enhanced instances also provide multiple enhanced data structure modules such as TairString, TairHash, TairGIS, TairBloom, and TairDoc. These modules help you improve the efficiency of business development. You no longer need to be concerned about storage structures and timeliness.
  • Persistent memory-optimized instances: Persistent memory-optimized instances adopt Intel® Optane™ DC persistent memory (AEP) to provide you with in-memory databases that have a large capacity and are compatible with open source Redis. A persistent memory-optimized instance does not use disks to implement data persistence. It saves up to 30% of costs compared with an ApsaraDB for Redis Community Edition instance and provides almost the same performance in terms of throughput and latency. This helps improve the reliability of business data.
  • Storage-optimized instances: Storage-optimized instances are developed based on ESSDs and compatible with core data structures and interfaces of open source Redis. These instances can provide large-capacity, low-cost, and persistent database services. Storage-optimized instances reduce costs and improve data reliability. In addition, storage-optimized instances reduce the amount of reserved memory that is required for the forks of native Redis databases.
