    The underlying architectures vary by Redis version. Once a Redis version is chosen, it cannot be changed. For example, you cannot upgrade a DCS Redis 3.0 instance to Redis 4.0 or 5.0. If you require a higher Redis version, create a new instance that meets your requirements and then migrate data from the old instance to the new one.

    DCS Redis 3.0 instances have been taken offline at new sites, but can still be used at existing sites. You are advised to use DCS Redis 4.0 and later instances.

  • Instance type

    Select from single-node, master/standby, and cluster types. For details about their architectures and application scenarios, see DCS Instance Types.
