When you use DTS to migrate data, the following types of traffic may be generated:

  • Inbound traffic: You are not charged for inbound traffic. For example, you are not charged for the traffic that is generated when you migrate data from an on-premises database to a self-managed database on an ECS instance or an Alibaba Cloud database over the Internet.
  • Traffic within Alibaba Cloud: You are not charged for traffic within Alibaba Cloud. For example, you are not charged for the traffic that is generated when you migrate an Alibaba Cloud database or a self-managed database on an ECS instance to another Alibaba Cloud database over the Internet.
Note You are charged Internet traffic fees based on the actual traffic that is generated. The unit price is USD 0.15 per GB. Traffic of less than 1 GB is charged as 1 GB.
