<p>This article describes how to create a whitelist.</p> <p><strong><span style="font-size:18px">Overview</span></strong></p> <p>After a DDS instance is created successfully, you can log in to DDS database to operate. Ping An Cloud DDS supports MongoDB agreement, so users can use any general MongoDB client to connect to the DDS instance. For security purposes, Ping An Cloud does not support direct connection from the public Internet but from Ping An Cloud ECS to DDS instance.</p> <p>By default, DDS is inaccessible. Therefore, you shall create a whitelist in the DDS management console and allow ESC to access the DDS instance. Using whitelists properly can improve DDS access security.</p> <p>The general instance and remote disaster recovery instance require you to create a whitelist.</p> <p><strong><span style="font-size:18px">Limitations</span></strong></p> <p>DDS is not available for BMS access in East China.</p> <p><strong><span style="font-size:18px">Prerequisites</span></strong></p> <p>1.&nbsp; You have successfully created the instance.
