This topic describes how to use ApsaraDB RDS with heterogeneous databases to store a wide range of data.
ApsaraDB RDS can be used with various Alibaba Cloud services, such as ApsaraDB for Redis, ApsaraDB for Memcache, and Object Storage Service (OSS), to store a wide range of data.
Persistence of cached data
You can use ApsaraDB RDS with ApsaraDB for Redis and ApsaraDB for Memcache to store data at high IOPS and low latency.
ApsaraDB for Redis and ApsaraDB for Memcache have the following advantages over ApsaraDB RDS:
ApsaraDB for Redis and ApsaraDB for Memcache can respond to queries at higher speeds. In most cases, the latency per query is less than a few milliseconds.
The caches of ApsaraDB for Redis and ApsaraDB for Memcache support larger numbers of queries per second (QPS).
For more information, see Cached data persistence.
Storage of data in different structures
OSS is a secure, cost-effective, and highly reliable cloud storage service that is provided by Alibaba Cloud. You can use ApsaraDB RDS together with OSS to store data in different structures.
For example, you can use ApsaraDB RDS together with OSS for a forum application. This way, you can store resources such as the images from user profiles and the images from posts in OSS buckets to reduce the amount of storage that is occupied in ApsaraDB RDS.
