Does DCS Support Public Access?

  • Redis 3.0

    Currently, public access is supported only by password-protected DCS Redis 3.0 instances. You can enable or disable SSL for public access. You are advised to download a CA certificate in advance and use it to verify the certificate of a DCS instance for security purposes. For more information, see Public Access to a DCS Redis Instance.

  • Redis 4.0 and later

    Currently, Redis 4.0 and later instances do not support direct public access. Single-node, master/standby, read/write splitting, and Proxy Cluster instances with password-protected enabled support public access through Elastic Load Balance (ELB). For details, see Enabling Public Access to Redis 4.0/5.0/6.0 and Obtaining the Access Addresses.

    Redis Cluster instances do not support public access.

  • Memcached

    Public access is not supported. The ECS that serves as a client and the DCS instance that the client will access must belong to the same VPC. In the application development and debugging phases, you can also use SSH to access your instance in the local environment. For details, see Using SSH Tunneling for Public Access to a DCS Instance.
