<p>This article describes how to create a whitelist entry.</p> <p><strong><span style="font-size:18px">Overview</span></strong></p> <p>After a Redis instance is created, you can log in to the Redis database to perform operations. The Ping An Cloud Redis service supports the open-source Redis protocol. You can use a general Redis client to connect to a Redis instance.</p> <p>For security reasons, Ping An Cloud currently does not support direct access to Redis instances from the public network. You can access the Redis instance only from an ECS instance.</p> <p>By default, the Redis service is not accessible. To allow an ECS instance to access a Redis instance, you must create a whitelist entry in the Redis console. The whitelist feature enhances the access security of the Redis service.</p> <p><strong><span style="font-size:18px">Limitations</span></strong></p> <p>Currently, BMS in the East China region does not support access to Redis.</p> <p><strong><span style="font-size:18px">Prerequisites</span></strong></p> <ol> <li>You have successfully created a Redis instance.
