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 5.0
Public access is not supported by DCS Redis 4.0 and 5.0 instances. If public access is required, use Nginx to redirect connections through an ECS configured with the same VPC and security group as the DCS instance. For details, see Using Nginx to Access DCS Redis 4.0 or 5.0 Instances over Public Networks.
- 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 phase, you can also use an SSH agent to access DCS instances in the local environment.
