    NOTE:

    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.

  • Instance type

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